DETAILED DESCRIPTION

[0018] Example 1: Figure 1 and Figure 2 The wall steel nail high frequency entry positioning hammer shown is a kind of electric drive continuous high frequency impact hammer head. As long as the parts include main body shell 1, handle, storage battery and motor 18, and hammer head 19 and other parts.

[0019] The main body shell 1 is used as a carrier component, mainly for supporting the hammer head 19, the battery and the motor 18 and the clamping mechanism at the front end.

[0020] The driving relationship between the hammer head 19 and the motor 18 can be seen in Figure 5 As shown, a fixed support is provided on the inner side of the main housing 1, and a front support seat 2 is fixed to the front end of the main housing 1. A guide hole is provided in the center of the fixed support and the front support seat 2, and a telescopic rod 20 is matched and fitted in the guide hole, and a hammer head 19 is fixed to the front end of the telescopic rod 20. A dynamic support is fixed to the middle of the telescopic rod 20, and a hammer push spring is connected between the dynamic support and the fixed support. In a natural state, the hammer push spring pushes the dynamic support to force the telescopic rod 20 and the hammer head 19 to extend forward.

[0021] A rack is provided on one side of the middle of the telescopic rod 20, and a half-toothed gear is installed on the inner wall of the main housing 1 on one side of the rack. The rotating shaft of the half-toothed gear is connected to the rotating shaft of the motor 18, and the motor 18 is fixed to the side of the main housing 1. A battery is installed in the main housing 1, and the power supply end of the battery is connected to the power supply of the motor 18 to form a circuit, and a switch is provided to control the opening and closing state of the circuit.

[0022] Among them, the half-toothed gear is provided with a gear on one part of the rotating wheel circumference and not provided with a gear on the other part, and is a smooth surface. Thus, when the motor 18 drives the gear to rotate, when the toothed surface of the gear meshes with the rack, the gear drives the rack to move backward, so that the telescopic rod 20 and the hammer head 19 move backward and compress the hammer push spring. During the continuous rotation of the half-toothed gear, when the smooth surface contacts the rack, the gear no longer drives the rack to move, and the hammer push spring releases pressure instantly. At this time, the telescopic rod 20 and the hammer head 19 suddenly impact forward to achieve the effect of impacting the end cap of the steel nail. The motor 18 can drive the gear through a gearbox, or it can directly drive the gear. When the gear is driven directly, the motor 18 can rotate one circle to make the telescopic rod 20 complete a telescopic movement, thereby achieving the purpose of high-frequency impact. When in use, there is no need for excessive hammering force, but the high-frequency impact effect is used to slow the steel nail into the wall, which is simple and convenient to operate, with low noise, and stable and reliable.

[0023] At the same time, if Figure 1 and Figure 2 As shown, hinged ears 3 are respectively provided on the upper and lower sides of the front side of the front end support seat 2, each hinged ear 3 is hinged with a rocker arm 4 through a pin shaft, and a torsion spring 17 is provided between the hinged ear 3 and the rocker arm 4 bracket to keep the rocker arm 4 contracted inwardly, and a flip rod 5 is respectively vertically connected to the front end of each rocker arm 4, and rear clamps 16 are respectively provided on the end faces opposite to the flip rods 5 on both sides.

[0024] Embodiment 2: Based on the improvement of the convenience of clamping nails by swinging the rear clamp in embodiment 1, a swingable component is provided at the front end of the device, and a composite component with advance and retreat functions and front and rear clamps 16 are provided to further ensure the stable advancement effect of the nail insertion process. Figure 1 and Figure 2 As shown, guide sleeves 15 parallel to the axial direction are respectively provided at the outer ends of the flip rods 5, and axial guide rods 6 are respectively installed in each guide sleeve 15. A radial guide tube 7 is respectively vertically connected to the front end of each axial guide rod 6, and an axial compression spring 8 is connected between each guide tube 7 and the corresponding guide sleeve 15. A radial guide rod 10 is respectively installed in each guide tube 7, and a front clamp 12 is provided at the inner end of each radial guide rod 10. A radial compression spring 13 is connected between the radial guide rod 10 and the front clamp 12, and an L-shaped wall support 11 is connected to the outer end of each guide rod. The front and rear clamps 16 are used to constrain the steel nails in a horizontal state, and the axial direction of the steel nails is always kept coincident with the axial direction of the hammer head 19, so that the hammer head 19 can continuously hammer the steel nails in the largest and most stable state.

[0025] The axial guide rod 6 is a screw rod, and an adjusting nut 9 is sleeved on the outside of the axial guide rod 6, and the adjusting nut 9 is located at the rear side of the guide sleeve 15. For steel nails of different lengths, the maximum distance adjustment of the front and rear clamps 16 can be achieved by controlling the position of the adjusting nut 9 at the upper end of the screw rod.

[0026] The stability of the device can be improved by adding a rubber pad 14 on the end surface of the L-shaped wall support 11, which has a buffering function and better protects the wall.

[0027] Embodiment 3: Based on embodiment 2, spherical teeth are symmetrically arranged on the inner concave surface of the front clamp head 12, and an anti-skid pad is installed in the area between the spherical teeth, and the height of the anti-skid pad is consistent with the height of the spherical teeth. A sawtooth-shaped tooth is arranged at the center of the inner concave surface of the rear clamp head 16.
