Description

Technical Field

[0001] The utility model relates to the technical field of anti - shake of electric drills, and particularly relates to an anti - shake structure for a hand - held electric drill. Background Art

[0002] An electric drill is a drilling tool powered by electricity. It is a conventional product among electric tools and also the electric tool product with the largest demand. When using a hand - held electric drill for drilling, both the hand and the electric drill are prone to shaking, resulting in the drill bit deviating. Therefore, an anti - shake structure for the hand - held electric drill is needed to prevent the hand - held electric drill from shaking.

[0003] Currently, a Chinese patent with the publication number CN217799140U discloses an anti - shake structure for an electric drill, which includes an annular groove and a drill bit arranged on the electric drill body. The side wall of the annular groove is detachably connected with a connecting ring through an installation mechanism, and one end of the connecting ring is fixedly connected with a support ring. The support ring is sleeved on the side wall of the electric drill body. The end of the support ring is connected with a moving ring through a telescopic mechanism, and the moving ring is sleeved on the side wall of the drill bit. In this anti - shake structure for the electric drill, when drilling, the moving ring is abutted against the drilling position. As the drilling progresses, the sleeve rod gradually moves into the sleeve. When the electric drill body shakes, the first spring deforms to play a shock - absorbing effect. At the same time, the moving disk slides in the sleeve. At this time, the damping oil flows along the through - hole to form a damping effect, making the shock - absorbing and anti - shake effect better.

[0004] After the applicant reviewed the Chinese patent with the publication number CN217799140U, the following problems were found: The surface of the moving ring proposed in the technical solution of the Chinese patent with the publication number CN217799140U is relatively smooth. During the process of pressing the electric drill after abutting the moving ring against the position to be drilled until the drill bit contacts the drilling position, the moving ring is prone to slipping, resulting in the deviation of the drilling position. Moreover, when pressing the electric drill, the elastic force of the first spring and the resistance generated by the damping oil make the pressing of the electric drill more laborious, affecting the drilling efficiency. Summary of the Utility Model

[0005] The utility model provides an anti - shake structure for a hand - held electric drill, aiming to solve the problems in the existing technical solution that the surface of the moving ring is relatively smooth. During the process of pressing the electric drill after abutting the moving ring against the position to be drilled until the drill bit contacts the drilling position, the moving ring is prone to slipping, resulting in the deviation of the drilling position. Moreover, when pressing the electric drill, the elastic force of the first spring and the resistance generated by the damping oil make the pressing of the electric drill more laborious, affecting the drilling efficiency and thus the use effect.

[0006] The present utility model is realized as follows. An anti-shake structure of a hand-held electric drill includes an electric drill body and a drill bit. A collar is sleeved on the surface of the electric drill body. A limiting mechanism is arranged at the rear side of the electric drill body, and a reinforcing plate is arranged at the front side of the limiting mechanism.

[0007] The limiting mechanism includes two fixing plates, a limiting ring and a plurality of anti-slip cones. The front side of the anti-slip cone is fixedly connected to the rear side of the limiting ring. One side of the fixing plate close to the limiting ring is fixedly connected to the limiting ring. The drill bit and the center point of the limiting ring are on the same straight line.

[0008] In order to achieve the effect of facilitating the connection between the collar and the electric drill body, as a preferred embodiment of the anti-shake structure of the hand-held electric drill of the present utility model, a limiting screw is arranged on the surface of the collar. One side of the limiting screw close to the collar passes through the collar and is in close contact with the surface of the electric drill body. The surface of the limiting screw is threadedly connected to the inner wall of the collar. The number of the limiting screws is four and they are evenly distributed inside the collar.

[0009] In order to achieve the effect of facilitating the pulling of the electric drill body to move, as a preferred embodiment of the anti-shake structure of the hand-held electric drill of the present utility model, an electric telescopic rod is fixedly connected to the rear side of the collar. The rear side of the telescopic end of the electric telescopic rod is fixedly connected to the front side of the limiting ring. The number of the electric telescopic rods is four and they are evenly distributed at the rear side of the collar.

[0010] In order to achieve the effect of making the movement of the electric drill body more stable, as a preferred embodiment of the anti-shake structure of the hand-held electric drill of the present utility model, the rear side of the reinforcing plate is fixedly connected to the front side of the limiting ring. The number of the reinforcing plates is four and they are evenly distributed at the front side of the limiting ring. A sliding groove is formed inside the collar. The surface of the reinforcing plate is slidably connected to the inside of the sliding groove.

[0011] In order to achieve the effect of facilitating the pressing of the fixing plate, as a preferred embodiment of the anti-shake structure of the hand-held electric drill of the present utility model, an anti-slip pad is fixedly connected to the front side of the fixing plate. The number of the anti-slip pads is a plurality and they are evenly distributed at the front side of the fixing plate.

[0012] In order to achieve the effect of making the reinforcing plate more durable, as a preferred embodiment of the anti-shake structure of the hand-held electric drill of the present utility model, the reinforcing plate is made of an inelastic wear-resistant plastic material.

[0013] In order to achieve the effect of facilitating the movement of the fixing plate, as a preferred embodiment of the anti-shake structure of the hand-held electric drill of the present utility model, through grooves are formed inside both of the two fixing plates.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The anti-shake structure of the hand-held electric drill connects the collar with the electric drill body. When the electric drill body is needed for drilling, the electric drill body is moved to the drilling position, so that the anti-slip cone behind the limit ring contacts the position where drilling is required. Then, the palm presses one side of the fixed plate, and then controls the drill bit to rotate continuously. At the same time, control the telescopic ends of the four electric telescopic rods to contract. Then, press the fixed plate with both hands to make the limit ring more stable. At this time, the anti-slip cone can be in close contact with the position where drilling is required. At this time, the movement of the electric drill body and the drill bit can be avoided. The contraction of the telescopic end of the electric telescopic rod can drive the electric drill body to move backward, so that the drill bit can perform drilling work on the position where drilling is required. The telescopic end of the electric telescopic rod drives the electric drill body to move, which can avoid the resistance when pressing the electric drill body, and avoid the problem that the surface of the moving ring in the prior art solution is relatively smooth. During the process of pressing the electric drill against the position where drilling is required until the drill bit contacts the drilling position, the moving ring is prone to slip, resulting in the deviation of the drilling position. And when pressing the electric drill, the elastic force of the first spring and the resistance generated by the damping oil will make the pressing of the electric drill more laborious, affecting the drilling efficiency.

In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution: an anti-shake structure of a hand-held electric drill, including an electric drill body 1 and a drill bit 6. A collar 2 is sleeved on the surface of the electric drill body 1. A limiting mechanism 4 is provided at the rear side of the electric drill body 1, and a reinforcing plate 5 is provided at the front side of the limiting mechanism 4;

[0026] The limiting mechanism 4 includes two fixing plates 401, a limiting ring 402 and a plurality of anti-slip cones 403. The front side of the anti-slip cone 403 is fixedly connected to the rear side of the limiting ring 402. One side of the fixing plate 401 close to the limiting ring 402 is fixedly connected to the limiting ring 402. The drill bit 6 and the center point of the limiting ring 402 are on the same straight line.

[0027] In this embodiment: By connecting the collar 2 to the drill body 1, when it is necessary to use the drill body 1 for drilling, move the drill body 1 to the drilling position so that the anti-slip cone 403 behind the limit ring 402 contacts the position where drilling is required. Then, press one side fixing plate 401 with the palm, and then control the drill bit 6 to rotate continuously. At the same time, control the telescopic ends of the four electric telescopic rods 3 to contract. Immediately, press the fixing plate 401 with both hands to make the limit ring 402 more stable. At this time, the anti-slip cone 403 can be in close contact with the position where drilling is required, and at this time, the movement of the drill body 1 and the drill bit 6 can be avoided. The contraction of the telescopic ends of the electric telescopic rods 3 can drive the drill body 1 to move backward, so that the drill bit 6 can perform drilling work on the position where drilling is required. The telescopic ends of the electric telescopic rods 3 drive the drill body 1 to move, which can avoid the resistance when pressing the drill body 1, and avoid the problem that the surface of the moving ring in the prior art solution is relatively smooth. During the process of pressing the drill against the position where drilling is required until the drill bit 6 contacts the drilling position, the moving ring is prone to slip, resulting in the deviation of the drilling position. And when pressing the drill, the elastic force of the first spring and the resistance generated by the damping oil will make the pressing of the drill more laborious, affecting the drilling efficiency.

[0028] As a technical optimization scheme of the present utility model, a limit screw 9 is provided on the surface of the collar 2. The side of the limit screw 9 close to the collar 2 passes through the collar 2 and is in close contact with the surface of the drill body 1. The surface of the limit screw 9 is threadedly connected to the inner wall of the collar 2. The number of limit screws 9 is four and they are evenly distributed inside the collar 2.

[0029] In this embodiment: By moving the drill body 1 so that the collar 2 is sleeved on the surface of the drill body 1, and then rotating the limit screw 9 so that the surface of the limit screw 9 is in close contact with the surface of the drill body 1, the collar 2 can be connected to the drill body 1, achieving the effect of facilitating the connection between the collar 2 and the drill body 1.

[0030] As a technical optimization scheme of the present utility model, an electric telescopic rod 3 is fixedly connected to the rear side of the collar 2. The rear side of the telescopic end of the electric telescopic rod 3 is fixedly connected to the front side of the limit ring 402. The number of electric telescopic rods 3 is four and they are evenly distributed on the rear side of the collar 2.

[0031] In this embodiment: By simultaneously controlling the telescopic ends of the four electric telescopic rods 3 to contract, the contraction of the telescopic ends of the electric telescopic rods 3 can drive the drill body 1 to move backward, achieving the effect of facilitating the movement of the drill body 1.

[0032] As a technical optimization solution of the present utility model, the rear side of the reinforcing plate 5 is fixedly connected to the front side of the limiting ring 402. The number of the reinforcing plates 5 is four and they are evenly distributed on the front side of the limiting ring 402. A chute 7 is provided inside the sleeve ring 2, and the surface of the reinforcing plate 5 is slidably connected to the inside of the chute 7.

[0033] In this embodiment: When the electric drill body 1 moves, the reinforcing plate 5 slides inside the chute 7, and the reinforcing plate 5 can make the movement of the electric drill body 1 more stable, achieving the effect of making the movement of the electric drill body 1 more stable.

[0034] As a technical optimization solution of the present utility model, an anti-slip pad 8 is fixedly connected to the front side of the fixing plate 401. The number of the anti-slip pads 8 is several and they are evenly distributed on the front side of the fixing plate 401.

[0035] In this embodiment: By contacting the surface of the palm with the anti-slip pad 8, it is convenient to press the fixing plate 401, achieving the effect of facilitating the pressing of the fixing plate 401.

[0036] As a technical optimization solution of the present utility model, the reinforcing plate 5 is made of non-elastic wear-resistant plastic material.

[0037] In this embodiment: Since the reinforcing plate 5 is made of non-elastic wear-resistant plastic, the reinforcing plate 5 can be made more durable, and the movement of the electric drill body 1 can be made more stable, achieving the effect of making the reinforcing plate 5 more durable.

[0038] As a technical optimization solution of the present utility model, through grooves 10 are provided inside both of the fixing plates 401.

[0039] In this embodiment: By passing a finger through the through groove 10, it is convenient to move the fixing plate 401, achieving the effect of facilitating the movement of the fixing plate 401.

[0040] Working principle: First, move the electric drill body 1 so that the collar 2 is sleeved on the surface of the electric drill body 1. Then, rotate the limit screw 9 so that the surface of the limit screw 9 is in close contact with the surface of the electric drill body 1, and the collar 2 can be connected to the electric drill body 1. When it is necessary to use the electric drill body 1 for drilling, move the electric drill body 1 to the drilling position so that the anti-slip cone 403 behind the limit ring 402 contacts the position to be drilled. Then, press one side of the fixed plate 401 with the palm, and then control the drill bit 6 to rotate continuously. At the same time, control the telescopic ends of the four electric telescopic rods 3 to contract. Then, press the fixed plate 401 with both hands to make the limit ring 402 more stable. At this time, the anti-slip cone 403 is in close contact with the position to be drilled. At this time, the movement of the electric drill body 1 and the drill bit 6 can be avoided. The contraction of the telescopic ends of the electric telescopic rods 3 can drive the electric drill body 1 to move backward, so that the drill bit 6 can perform drilling work on the position to be drilled. At this time, the reinforcing plate 5 slides inside the chute 7, and the reinforcing plate 5 can make the movement of the electric drill body 1 more stable, avoiding the displacement of the drill bit 6 during the contact between the drill bit 6 of the electric drill body 1 and the position to be drilled, resulting in the offset of the hole. The telescopic ends of the electric telescopic rods 3 drive the electric drill body 1 to move, which can avoid the resistance when pressing the electric drill body 1, avoiding the problem that the surface of the moving ring in the prior art solution is relatively smooth, and during the process of pressing the electric drill against the position to be drilled until the drill bit 6 contacts the drilling position, the moving ring is prone to slip, resulting in the offset of the drilling position, and when pressing the electric drill, the elastic force of the first spring and the resistance generated by the damping oil will make the pressing of the electric drill more laborious, affecting the drilling efficiency.

[0041] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
