[0026] In this utility model, "upper" and "lower" refer to... Figure 1 The markings in the text shall prevail.

[0027] The following is based on Figures 1 to 8 This invention describes the drilling rig in detail.

[0028] In this embodiment, such as Figure 1 As shown, the drill 100 includes a base 1, a drill body 2, and a handle 3. The base 1 forms a support structure and includes a base shell 11. The drill body 2 is used for drilling and is movably mounted on the base 1. The base 1 can be an electromagnetic base, which generates a strong magnetic force when energized, allowing it to adhere to magnetic workpieces such as steel, providing a stable drilling foundation. When the drill 100 is placed on a horizontal surface, the drill body 2 and the handle 3 are located on opposite sides of the base 1. The drill body 2 can move up and down to adjust the distance between the drill body 2 and the workpiece.

[0029] like Figures 2 to 4 As shown, the handle 3 includes a handle body 31 and a handle shell 32. The handle body 31 is integrally formed with the base shell 11. The handle body 31 has high structural strength. The handle shell 32 is detachably connected to the handle body 31. The handle shell 32 at least partially covers the handle body 31, that is, the handle shell 32 can partially cover the handle body 31 or completely cover the handle body 31.

[0030] The above technical solution improves the structure of the handle 3. The handle 3 includes a detachably connected handle body 31 and handle shell 32. The handle body 31, which is integrally formed with the base shell 11, is used to form the main structure of the handle 3 to ensure the structural strength of the handle 3. The handle shell 32 provides protection for the handle body 31. When the handle shell 32 is damaged, it can be replaced in time to reduce replacement costs.

[0031] In one implementation, such as Figure 3 and Figure 4 As shown, the handle housing 32 is sleeve-shaped and is fitted around the outer periphery of the handle body 31 to improve the protection of the handle body 31.

[0032] Furthermore, such as Figure 3 As shown, the handle body 31 is completely or as much as possible located within the handle housing 32, which can fully protect the handle body 31 and reduce the probability of damage to the handle body 31.

[0033] In one embodiment, both the base 1 and the handle body 31 are metal parts, and the handle body 31 has high structural strength and is not easily damaged.

[0034] In one embodiment, the handle body 31 is made of aluminum, which satisfies the requirements of lightweight design and high structural strength. Furthermore, the main body of the base 1 is made of aluminum, and the base of the base 1 is at least provided with an electromagnet for attracting magnetic metal workpieces.

[0035] In one implementation, such as Figure 1 As shown, when the base 1 is supported on a horizontal surface, the angle between the extension direction of the handle 3 and the horizontal surface is 0°-40°, which is convenient for the user to hold. Furthermore, when the base 1 is supported on a horizontal surface, the handle 3 extends downward at an angle away from the connection between the handle 3 and the base 1.

[0036] In one embodiment, the handle housing 32 is made of resin, which is lightweight, low-cost, and has good impact resistance. Thus, without changing the thickness of the handle body 31 compared to the thickness of handles in the prior art, by adding the handle housing 32, the thickness of the handle 3 can be increased without a significant increase in weight, thereby improving the grip.

[0037] In one implementation, such as Figure 3 and Figure 5 As shown, the surface of the handle body 31 is provided with multiple grooves 313. The grooves 313 are used to reduce the weight of the handle body 31, which helps to reduce the overall weight of the machine and reduce the burden on the user. Furthermore, in order to ensure the structural stability of the handle body 31, the handle body 31 has a symmetrical structure, and all handle bodies 31 have grooves 313 on the left and right sides respectively.

[0038] In one implementation, such as Figure 3 As shown, the end of the handle housing 32 extends away from the end of the handle body 31 to increase the length of the handle 3. In this solution, the handle housing 32 serves to provide protection for the handle body 31 on the one hand, and on the other hand, it can increase the length of the handle 3 and improve the grip comfort.

[0039] In one implementation, such as Figure 3 and Figure 6 As shown, the inner wall of the handle housing 32 is provided with at least two engaging protrusions 3211; the at least two engaging protrusions 3211 form a counteracting force to engage the handle body 31. The number of engaging protrusions 3211 can be two, three, four, or even more, and the number can be either even or not. To ensure the stability of the engagement, the number of engaging protrusions 3211 is even, with two engaging protrusions 3211 forming a group, forming a counteracting force. The two engaging protrusions 3211 in the same group abut against the two side walls of the handle body 31 respectively to achieve engagement.

[0040] Furthermore, such as Figure 3 and Figure 4As shown, the drilling rig 100 also includes a pressing member 4 and a locking member 5. The locking member 5 is used to lock the pressing member 4 to the handle body 31, so that the pressing member 4 presses against the locking protrusion 3211 along the installation direction of the handle housing 32, thereby preventing the handle housing 32 from detaching from the handle body 31. The pressing member 4 is used to distribute the pressing force on the locking protrusion 3211, avoiding stress concentration on the locking protrusion 3211, which could easily cause damage to the locking protrusion 3211. Specifically, the assembly of the handle body 31 and the handle housing 32 is first pre-assembled by locking the locking protrusion 3211, and then the pressing member 4 and the locking member 5 are used to lock the handle housing 32 onto the handle body 31, ensuring the stability of the assembly of the handle housing 32.

[0041] Furthermore, such as Figure 3 and Figure 5 As shown, the handle body 31 includes a first end 311 and a second end 312 spaced apart along the direction away from the base housing 11. The locking member 5 is used to lock the pressing member 4 onto the end face of the second end 312, so that the pressing member 4 presses against the snap-fit ​​protrusion 3211 along the installation direction of the handle housing 32, so as to ensure that the locking member 5 can be stably locked onto the second end 312 of the handle body 31.

[0042] Furthermore, such as Figure 3 and Figure 5 As shown, the first end 311 is provided with an abutment boss 3111; the pressing member 4 presses against the engagement protrusion 3211 so that one end of the handle housing 32 abuts against the abutment boss 3111 along the installation direction of the handle housing 32. Specifically, the second end 312 of the handle body 31 is locked to the handle housing 32 by the locking member 5, and the first end 311 of the handle body 31 abuts against the end of the handle housing 32 by the abutment boss 3111, thereby installing the handle housing 32 on the handle body 31. The assembly of the handle housing 32 is convenient and stable.

[0043] Furthermore, such as Figure 3 and Figure 5 As shown, the first end 311 is provided with a snap-fit ​​boss 3112, which has a circumferential outer contour. One end of the handle housing 32 is fitted onto the snap-fit ​​boss 3112. Specifically, the second end 312 of the handle body 31 snaps into the snap-fit ​​protrusion 3211 provided inside one end of the handle housing 32, and the first end 311 of the handle body 31 snaps into the other end of the handle housing 32 through the snap-fit ​​boss 3112, so as to ensure that the handle housing 32 and the handle body 31 can be stably snapped together, and to prevent the handle housing 32 from shaking.

[0044] Furthermore, such as Figure 3 and Figure 5As shown, the abutment boss 3111 includes at least a first abutment surface 31111 and a second abutment surface 31112, with the second abutment surface 31112 inclined relative to the first abutment surface 31111. The end face of the handle housing 32 facing the abutment boss 3111 matches the shape of the abutment boss 3111, and the end face of the engaging boss 3112 has the same or approximately the same outline as the abutment surface of the abutment boss 3111. In this solution, by optimizing the shape of the abutment boss 3111 and setting the abutment surfaces of the handle housing 32 and the abutment boss 3111 to match each other, a foolproof mechanism can be implemented when assembling the handle body 31 and the handle housing 32. The operator simply matches and aligns the shape of this end of the handle housing 32 with the shape of the abutment boss 3111 and then slips the handle housing 32 on. In addition, setting the end face of the snap-fit ​​boss 3112 to be the same or approximately the same shape as the abutment surface of the abutment boss 3111 can improve the aesthetics of the outer contour of the handle body 31.

[0045] In one implementation, such as Figure 3 As shown, the end face of the second end 312 and the end face of the snap-fit ​​protrusion 3211 opposite to the first end 311 are flush to ensure that both the snap-fit ​​protrusion 3211 and the second end 312 of the handle body 31 can effectively abut against the pressing member 4.

[0046] In one implementation, such as Figures 3 to 5 As shown, the second end 312 is provided with a mounting hole 3121, and the locking member 5 is a fastener (such as a bolt). The locking member 5 cooperates with the mounting hole 3121 to lock the pressing member 4 onto the end face of the second end 312. The assembly is convenient and the assembly cost is low. It should be explained that the installation method of the "fastener" in this article is a detachable connection method, which can be disassembled and assembled with the help of tools such as screwdrivers. Furthermore, such as Figures 3 to 5 As shown, the locking element 5 is a bolt, and the drilling rig 100 also includes a nut 6. The locking element 5 and the nut 6 cooperate to achieve locking. The handle body 31 is provided with a receiving cavity 314, and the nut 6 is snapped into the receiving cavity 314. The cavity wall of the receiving cavity 314 is used to restrict the rotation of the nut 6. In this way, when the locking element 5 is screwed into the nut 6, the receiving cavity 314 restricts the nut 6 from rotating, and the user does not need to manually restrict the nut 6. Furthermore, in a specific embodiment, after the handle housing 32 is put on the handle body 31, the nut 6 is blocked by the handle housing 32, and the user cannot operate the nut 6. Therefore, this solution restricts the rotation of the nut 6 by providing a receiving cavity 314.

[0047] In one implementation, such as Figure 3 and Figure 6As shown, the snap-fit ​​protrusion 3211 is elongated, and its length extends along the length direction of the handle body 31. Specifically, the locking member 5 locks the pressing member 4 onto the second end 312 of the handle body 31. The locking member 5 applies a force to the pressing member 4 along the length direction of the handle body 31, causing the pressing member 4 to press against the snap-fit ​​protrusion 3211 along the length direction of the handle body 31. This solution improves the bearing capacity of the snap-fit ​​protrusion 3211 in the length direction of the handle body 31 by setting the length of the snap-fit ​​protrusion 3211 to extend along the length direction of the handle body 31, thereby improving the structural stability of the snap-fit ​​protrusion 3211.

[0048] In one implementation, such as Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the handle housing 32 includes a housing 321 and a handle cover 322. The housing 321 has a mounting cavity 3212. The assembly point between the handle body 31 and the handle housing 32 is located within the mounting cavity 3212. The handle cover 322 is interference-fitted with the mounting cavity 3212, and the handle cover 322 covers the assembly point between the handle body 31 and the handle housing 32 to improve the aesthetic appearance of the handle 3. A first abutment portion 3213 is provided within the mounting cavity 3212, and the handle cover 322 abuts against the first abutment portion 3213 along the mounting direction of the handle cover 322. The handle cover 322 has a first region 3221 and a second region 3222, which are located on both sides of the first abutment portion 3213, respectively. The interference fit between the first region 3221 and the mounting cavity 3212 is smaller than the interference fit between the second region 3222 and the mounting cavity 3212. When an external force presses inward on the first area 3221, the handle cover 322 flips around the first abutment portion 3213, and a portion of the handle cover 322 can detach from the housing 321. The user can then use their hands or tools to grip the handle cover 322 and pull it outward to remove it, exposing the assembly point between the handle body 31 and the handle housing 32, thus allowing the handle housing 32 to be disassembled. When it is necessary to reinstall the handle cover 322 onto the housing 321, the handle cover 322 is snapped into the housing 321 along the installation direction until it is in contact with the first abutment portion 3213, indicating that it is properly installed.

[0049] The above technical solution optimizes the structure of the handle housing 32, limits the interference fit between the first area 3221 and the second area 3222 of the handle cover 322 and the housing 321 to be different, and sets the handle cover 322 to abut against the first abutting part 3213 of the housing 321, so that the handle cover 322 of the handle housing 32 can be disassembled by flipping, exposing the assembly point of the handle body 31 and the handle housing 32, thereby allowing the handle housing 32 to be removed. The disassembly method of the handle cover 322 is simple and quick, requires little modification to the handle housing 32, and is beneficial to cost control.

[0050] In one implementation, such as Figure 3 and Figure 8 As shown, the handle cover 322 is positioned near the end face of the housing 321. When the handle cover 322 is flipped, the second area 3222 extends at least partially outside the mounting cavity 3212. The portion of the handle cover 322 extending outside the mounting cavity 3212 allows the user to easily grasp it or clamp it with a tool, facilitating quick disassembly. Of course, when the handle cover 322 is flipped, the second area 3222 may not extend into the mounting cavity 3212. In this case, the user can use tools such as tweezers to reach into the housing 321 to clamp the handle cover 322 and pull it out.

[0051] In one implementation, such as Figures 6 to 8 As shown, the mounting cavity 3212 is provided with a second abutment 3214. The second area 3222 abuts against the second abutment 3214 along the mounting direction of the handle cover 322. The second abutment 3214 is used to prevent the second area 3222 from moving inward. In this way, when an external force presses the first area 3221 inward, the handle cover 322 as a whole can be prevented from moving inward, thus avoiding the inability to flip smoothly. In fact, the inward movement of the handle cover 322 as a whole increases the difficulty of disassembling the handle cover 322. That is, by setting the second abutment 3214, it is ensured that the handle cover 322 can only flip, thereby ensuring that the handle cover 322 can be disassembled smoothly.

[0052] Furthermore, such as Figures 6 to 8 As shown, the handle cover 322 has a first end 3223 and a second end 3224 disposed opposite to each other. The first end 3223 is located in the first region 3221, and the second end 3224 is located in the second region 3222. The second abutting part 3214 abuts against the inner side of the second end 3224 to ensure stable abutment.

[0053] In one implementation, such as Figure 6 As shown, there are two first abutment portions 3213, and the two first abutment portions 3213 are respectively disposed on both sides of the cavity wall of the mounting cavity 3212.

[0054] Furthermore, such as Figure 7 and Figure 8 As shown, the two first abutment portions 3213 form a first axis X, and the handle cover 322 flips around the first axis X under external force. The distance between the first end 3223 of the handle cover 322 and the first axis X is greater than the distance between the second end 3224 of the handle cover 322 and the first axis X. That is, the first abutment portion 3213 is set close to the first end 3223, which can increase the difficulty of flipping the handle cover 322 and prevent the handle cover 322 from flipping due to accidental contact.

[0055] In one embodiment, the outer periphery of the handle cover 322 is press-fitted with the mounting cavity 3212 through a protruding structure. In this way, while achieving the purpose of engaging the handle cover 322 with the housing 321, the contact area between the handle cover 322 and the housing 321 is reduced, making it easier to control the force required to flip the handle cover 322 and pull out the handle cover 322 within a reasonable range.

[0056] Furthermore, such as Figure 8 As shown, the first region 3221 has a plurality of first protrusions 3225, and the second region 3222 has a plurality of second protrusions 3226. The total interference fit between all the first protrusions 3225 and the mounting cavity 3212 is less than the total interference fit between all the second protrusions 3226 and the mounting cavity 3212, such that the interference fit between the first region 3221 and the mounting cavity 3212 is less than the interference fit between the second region 3222 and the mounting cavity 3212.

[0057] Furthermore, such as Figure 8 As shown, at least two first protrusions 3225 are located on both sides of the first region 3221 and are opposite to each other, and at least two second protrusions 3226 are located on both sides of the second region 3222 and are opposite to each other, so as to improve the stability of the engagement between the handle cover 322 and the housing 321.

[0058] Furthermore, such as Figure 8 As shown, the handle cover 322 has a first end 3223 located in the first region 3221, and a portion of the first protrusion structure 3225 is provided on the end face of the first end 3223. Specifically, the two sides of the first region 3221 are interference-fitted with the mounting cavity 3212 of the housing 321. At the same time, the first end 3223 of the first region 3221 is also interference-fitted with the mounting cavity 3212. Compared with the scheme of providing the first protrusion structure 3225 only on the two sides of the first region 3221 or only at the first end 3223 of the first region 3221, this scheme can reduce the interference amount distributed by each first protrusion structure 3225 by increasing the contact points between the first region 3221 and the housing 321. This reduces the manufacturing precision requirements of the first protrusion structure 3225 on the first region 3221, reduces the force required for loading and unloading, and facilitates loading and unloading.

[0059] In one specific implementation, such as Figure 8 As shown, two first protrusion structures 3225 form a group of protrusions, a group of protrusions is provided on each side of the first area 3221, two groups of protrusions are provided at the first end 3223, two second protrusion structures 3226 form a group of protrusions, and a group of protrusions is provided on each side of the second area 3222. That is, the handle cover 322 has six groups of protrusions, for a total of twelve protrusion structures. Of course, the arrangement and number of protrusion structures are not limited to this, and other reasonable solutions can also be used.

[0060] In one implementation, such as Figure 8 As shown, the handle cover 322 has an inclined surface 3227 on the outer periphery of the side facing the housing 321, and the inclined surface 3227 is inclined inward in the direction towards the housing 321. In this way, when the first section 3221 of the handle cover 322 is flipped inward, the inclined surface 3227 of the second section 3222 can slide along the cavity wall of the mounting cavity 3212, avoiding jamming and reducing the noise generated by flipping.

[0061] In one implementation, such as Figure 3 , Figure 5 and Figure 8 As shown, the bottom wall at the end of the housing 321 extends downward at an angle to form an extension wall 3215, causing the end of the housing 321 to expand in a direction away from the drill body. This extension wall 3215 can, to some extent, prevent the handle 3 from slipping out of the user's hand when holding the handle 3, improving safety during use. The first region 3221 is located above the second region 3222, which is at least partially opposite to the extension wall 3215. Specifically, because the extension wall 3215 extends at an angle, the lower space at the end of the mounting cavity 3212 is limited, while the upper space at the end of the mounting cavity 3212 is relatively large. Furthermore, since the first region 3221 needs to be flipped inward and the second region 3222 flipped outward, placing the first region 3221 above the second region 3222 utilizes the upper space at the end of the mounting cavity 3212 for the first region 3221 to flip inward, fully utilizing the space of the mounting cavity 3212 and avoiding waste.

[0062] In one implementation, such as Figure 3 As shown, the locking element 5 is located in the mounting cavity 3212, and the handle cover 322 covers the locking element 5. Thus, when it is necessary to remove the handle housing 32, the handle cover 322 can be flipped over and removed to expose the locking element 5. The locking element 5 can then be removed with the help of tools to remove the handle housing 32.
