DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following further describes the present invention in detail with reference to the accompanying drawings.

[0035] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0036] Referring to Figures 1-5 As shown, a telescopic stud welding gun in a preferred embodiment of the present utility model includes a body mechanism 1. A positioning mechanism 2 is movably connected to the outer end of the body mechanism 1, and a telescopic mechanism 3 is movably connected to the rear end of the body mechanism 1;

[0037] The telescopic mechanism 3 includes an assembly block 301. The assembly block 301 is located at the rear end of the body mechanism 1. A reinforcing block 302 is movably connected to the outer end of the assembly block 301. Symmetrically distributed clamping posts 303 are installed at the outer end of the reinforcing block 302. A clamping groove 304 is formed at the outer end of the clamping post 303. The clamping groove 304 is located at the inner end of the assembly block 301. Symmetrically distributed positioning rods 305 are slidably connected to the inner end of the assembly block 301. A clamping head 306 is installed at the front end of the positioning rod 305.

[0038] Referring to Figures 3-4 As shown, further, an elastic ring 307 is sleeved on the outer end of the positioning rod 305, and a guiding ring 308 is slidably connected to the front side of the elastic ring 307.

[0039] Referring to Figure 4 As shown, further, the guiding ring 308 is located at the outer end of the positioning rod 305, and an adjusting groove 309 is formed at the outer end of the guiding ring 308. The adjusting groove 309 is located at the inner end of the assembly block 301.

[0040] Referring to Figures 1-2 As shown, further, an automatic telescopic rod 310 is installed at the rear end of the reinforcing block 302. A sliding frame 311 is movably connected below the automatic telescopic rod 310. The bottom end of the sliding frame 311 is slidably connected to a support 312.

[0041] By pulling a pair of positioning rods 305, the positioning rods 305 move under the action of the elastic ring 307, driving the chuck 306, so that the chuck 306 releases the fixing restriction with the clamping column 303. At this time, the clamping column 303 is taken out from the inner end of the assembly block 301, and the elastic ring 307 can move simultaneously with the adjustment of the positioning rod 305. When the external force acting on the positioning rod 305 is lost, the elastic ring 307 makes the positioning rod 305 rebound and position at the inner end of the clamping column 303, making the installation between the body mechanism 1 and the telescopic mechanism 3 more convenient and fixed, and thus enabling the stud welding gun body 101 and the telescopic mechanism 3 to be disassembled conveniently. The telescopic structure of this device is also relatively convenient to install. When this device performs telescopic work, the carriage 311 at the bottom of the mounting frame 201 slides on the outer end of the support 312 with the movement of the automatic telescopic rod 310, making the telescopic work of the body mechanism 1 more stable.

[0042] Refer to Figure 1 As shown, further, the body mechanism 1 includes a stud welding gun body 101. A handle 102 is installed at the bottom end of the stud welding gun body 101, and a welding nail chuck 103 is installed at the front end of the stud welding gun body 101.

[0043] By installing the handle 102, it is convenient to assemble and position the stud welding gun body 101 with the telescopic structure.

[0044] Refer to Figures 1-2 As shown, further, an assembly frame 201 is movably connected below the stud welding gun body 101. A driving member 202 is installed at the outer end of the assembly frame 201, and a screw rod 203 is installed at the transmission end of the driving member 202.

[0045] Refer to Figure 2 and Figure 5 As shown, further, symmetrically distributed positioning clips 204 are sleeved on the outer end of the screw rod 203. An anti - detachment piece 205 is slidably connected to the inner side of the positioning clip 204, and a buffer rod 206 is installed at the rear end of the anti - detachment piece 205.

[0046] Refer to Figure 5 As shown, further, a damping member 207 is installed at the rear end of the buffer rod 206. A buffer groove 208 is opened at the outer end of the damping member 207, and the buffer groove 208 is located at the inner end of the positioning clip 204.

[0047] By installing a pair of positioning clips 204 for position adjustment, the anti - detachment piece 205 is positioned at both ends of the handle 102. When the stud welding gun body 101 generates vibration force during use, the buffer rod 206 conducts the vibration force to the damping member 207, and the damping member 207 buffers and suppresses the acting force.

[0048] Specific implementation process: When the stud welding gun body 101 is connected to the telescopic structure, the clamping post 303 arranged outside the reinforcement block 302 at the front end of the automatic telescopic rod 310 is clamped inside the assembly block 301. The elastic ring 307 can move simultaneously with the adjustment of the positioning rod 305. When the external force acting on the positioning rod 305 is lost, the elastic ring 307 enables the positioning rod 305 to rebound and be positioned at the inner end of the clamping post 303, making the installation between the body mechanism 1 and the telescopic mechanism 3 more convenient and fixed. Then, start the driving member 202 to rotate the screw rod 203 with opposite threads, driving a pair of external positioning clips 204 to adjust their positions and driving the anti-slip piece 205 to be positioned at both ends of the handle 102. When the stud welding gun body 101 generates vibration force during use, the buffer rod 206 conducts the vibration force to the damping member 207, and the damping member 207 buffers and suppresses the acting force, enabling the stud welding gun body 101 to be more stable during positioning.

[0049] Finally, when the stud welding gun body 101 needs to be disassembled from the telescopic structure, pull a pair of positioning rods 305. The positioning rods 305 move under the action of the elastic ring 307, driving the chuck 306, so that the chuck 306 releases the fixed restriction from the clamping post 303. At this time, then take out the clamping post 303 from the inner end of the assembly block 301, and the stud welding gun body 101 can be conveniently disassembled from the telescopic mechanism 3. The installation of the telescopic structure of this device is also relatively convenient, improving the use convenience of this retractable stud welding gun.
