[0032] When the lithium battery wireless operation hand gun drill is used for drilling a metal plate, the vibration of the hand gun drill is easy to cause the drill bit to be inclined, meanwhile, in the drilling process, the staff cannot keep the drill bit parallel to the drilling direction for a long time because the hand gun drill is pressed and the strength is lost, so that the drill bit is jammed in the hole, and the hand gun drill is self-rotated due to inertia, which causes harm to the operator, therefore, the sliding rod 104 slidably connected with the outer wall of the driving rod 106 is arranged, and the vibration is transmitted to the spring one 109 through the sliding rod 104 and the sliding sleeve two 107, so that the vibration transmission is reduced, the vibration of the gun body 100 is prevented in the drilling process, the drill bit is prevented from being deviated, and the drill bit is prevented from being jammed.
[0033] The outer wall of the sliding sleeve one 102 is provided with a supporting mechanism 200.
[0034] When the lithium battery wireless operation hand gun drill is used for drilling a metal plate, the vibration of the hand gun drill is easy to cause the drill bit to be inclined, meanwhile, in the drilling process, the staff cannot keep the drill bit parallel to the drilling direction for a long time because the hand gun drill is pressed and the strength is lost, so that the drill bit is jammed in the hole, and the hand gun drill is self-rotated due to inertia, which causes harm to the operator, therefore, the supporting mechanism 200 is arranged, the gun body 100 is supported, the friction force with the surface of the metal plate is increased through the wave-shaped surface of the pressing plate 204 and the pressing block 207, the impact force generated by the self-rotation of the gun body 100 is discharged to the surface of the metal plate through the pressing plate 204 and the pressing block 207 when the drill bit is jammed, the recoil impact force generated by the jamming of the drill bit in the drilling process is prevented from being too large, and harm to the staff is avoided.
[0035] The support mechanism 200 includes a sliding sleeve 3 201, the inner wall of which is slidably connected to the outer wall of sliding sleeve 1 102. A positioning block 202 is inserted into the inner wall of the sliding sleeve 3 201, and the outer wall of the positioning block 202 is fixedly connected to the inner wall of the support sleeve 101 by threads. A support rod 203 is fixedly connected to the outer wall of the sliding sleeve 3 201. A pressure plate 204 is fixedly connected to the end of the support rod 203 away from the sliding sleeve 3 201. The outer wall of the pressure plate 204 is wavy and is used to contact the drilling surface and increase the friction with the surface. A motor and transmission components are installed inside the gun body 100 and are connected to the drive rod 106 near the end of the gun body 100 to drive the drive rod 106 to rotate. A limit groove 2 110 is formed on the outer wall of the sliding sleeve 1 102. The outer wall of the positioning block 202 slides along the groove wall of the limit groove 2 110, and the inner wall of the pressure plate 204 slides along the outer wall of the sliding sleeve 1 102. A guide block 205 is slidably connected to the outer wall of the support rod 203. A pressure block 207 is fixedly connected to the inner wall of the guide block 205. The outer wall of the pressure block 207 slides along the inner wall of the sliding sleeve 102. The end of the pressure block 207 away from the support sleeve 101 is wavy, which is used to contact the drilling surface and increase friction. A spring 3 208 is fixedly connected to the inner wall of the pressure block 207. The other end of the spring 3 208 is fixedly connected to the outer wall of the stop block 111 near the support sleeve 101. A limit block 206 is fixedly connected to the outer wall of the support rod 203. The limit block 206 is used to support the guide block 205, so that the guide block 205 drives the pressure block 207 to slide on the inner wall of the sliding sleeve 102 and contact the metal drilling surface. A limit groove 3 113 is opened on the outer wall of the sliding sleeve 102. The outer wall of the guide block 205 slides along the groove wall of the limit groove 3 113. The limit groove 3 113 is used to guide the guide block 205.
[0036] When the lithium-ion battery-operated wireless pistol drill is put into use, the drill bit is installed in the chuck 105 and aligned with the drilling area on the metal plate. The operator presses the drill body 100, causing the chuck 105 to drive the sliding rod 104 to slide towards the drill body 100 on the outer wall of the drive rod 106. At the same time, the sliding rod 104 drives the sliding sleeve 107, which is guided through the limiting groove 108 and compresses the spring 109 on the outer wall of the guide sleeve 103, causing the drill bit and chuck 105 to retract into the sliding sleeve 102. The outer wall of the sliding sleeve 102 then fits against the metal plate machining surface. After the sliding sleeve 102 fits against the metal machining surface, pressing the drill body 100 further compresses the support sleeve 101, which in turn compresses the spring 112 on the sliding sleeve 102. The inner wall slides, causing the sliding sleeve 201 to drive the positioning block 202 to slide on the inner wall of the limiting groove 110, and supporting the support rod 203. The support rod 203 then drives the pressure plate 204 to slide on the outer wall of the sliding sleeve 102 towards the metal plate, contacting the machined surface of the metal plate. Simultaneously, the pressure block 207 is supported by the spring 208, causing the support rod 203 to slide on the inner wall of the guide block 205 towards the metal plate. This causes the support rod 203 to drive the limiting block 206 to contact the outer wall of the guide block 205, driving the guide block 205 to slide in the limiting groove 113 towards the metal plate. The guide block 205 then drives the pressure block 207 to press the spring 208 against the sliding sleeve 102, causing the pressure block 207 to contact the machined surface of the metal plate. The pressure plate 204 and the pressure... After block 207 contacts the surface of the metal plate, pressure plate 204 supports support sleeve 101 via support rod 203 and sliding sleeve 201. At this time, the operator maintains pressure on gun body 100 and presses the switch of gun body 100 to start the motor installed inside gun body 100 as a power source. The motor drives drive rod 106 to rotate through transmission components. Drive rod 106 drives sliding rod 104 and chuck 105 to rotate via splines, causing chuck 105 to drive drill bit to drill into the metal plate. During the drilling process, the supporting force of spring 109 on sliding sleeve 107 causes sliding sleeve 107 to drive sliding rod 104 to slide on the outer wall of drive rod 106, thus drilling into the metal plate. During drilling operations, the vibrations generated are transmitted to the spring 109 via the sliding rod 104 and the second sliding sleeve 107 for damping, reducing vibration transmission and preventing vibration of the drill body 100 during drilling, which could cause the drill bit to deviate or jam. Iron filings generated during drilling of the metal plate by the chuck 105 are collected by the sliding sleeve 102 to prevent iron filings from splashing and polluting the environment. However, if the drill bit vibrates during drilling, and this vibration is transmitted to the drill body 100, causing the operator to lose control and the drill bit to deviate and jam, the drill body 100 may rotate, potentially causing injury to the operator.By having the operator press the drill body 100, the pressure plate 204 and pressure block 207 come into contact with the metal plate surface. The corrugated surfaces of the outer walls of the pressure plate 204 and pressure block 207 increase the friction with the metal plate surface. When the drill bit jams, the impact force generated by the partial rotation of the drill body 100 is dissipated to the metal plate surface through the pressure plate 204 and pressure block 207, preventing excessive back impact force from causing injury to the operator during drilling.
[0037] Example 2, based on Example 1, please refer to... Figures 5-7 and Figure 9 The present invention provides a technical solution: a connecting groove 115 is provided on the outer wall of the sliding sleeve 102, a positioning groove 117 is provided on the outer wall of the sliding sleeve 102, an insert block 114 is fixedly connected to the outer wall of the sliding sleeve 102, and a collection mechanism 300 is provided on the outer wall of the sliding sleeve 102.
[0038] During the drilling process, the support mechanism 200 comes into contact with the metal plate processing surface. If too much iron filings are collected inside the sliding sleeve 102, they will wrap around the outer wall of the sliding rod 104, causing the sliding rod 104 to jam. Therefore, a collection mechanism 300 is set up to collect the iron filings and can be quickly installed and disassembled to quickly clean up the iron filings.
[0039] The collection mechanism 300 includes a collection box 301. A slot 303 is provided on the inner wall of the collection box 301. The slot wall of the slot 303 is inserted into the outer wall of the insert block 114. The inside of the collection box 301 is connected to the inside of the sliding sleeve 102 through a connecting groove 115. The collection box 301 is used to collect iron filings. A positioning block 116 is fixedly connected to the outer wall of the sliding sleeve 102. A positioning hole 302 is provided on the outer wall of the collection box 301. The hole wall of the positioning hole 302 is inserted into the outer wall of the positioning block 116. The positioning block 116 is used to position the collection box 301 by inserting into the positioning hole 302. An elastic locking block 304 is fixedly connected to the inner wall of the collection box 301 by threads. One end of the elastic locking block 304 protrudes from the inner wall of the elastic locking block 304 near the sliding sleeve 102 and is inserted into the inner wall of the positioning groove 117. The elastic locking block 304 is used to lock the collection box 301 through the positioning groove 117.
[0040] When the chuck 105 drives the drill bit to drill a hole in the metal plate, the iron filings are collected by the sliding sleeve 102. At the same time, the vortex generated during the drilling process blows the iron filings through the connecting groove 115 into the collection box 301 for collection. After the drilling is completed, the sliding collection box 301 releases the insert 114 from the slot 303. At the same time, the collection box 301 drives the elastic locking block 304 to release the positioning groove 117. The collection box 301 is then removed, and the iron filings inside the collection box 301 are cleaned. The collection box 301 is then reinstalled to continue collecting iron filings.
