[0028] Reference Figs. 1 to 4 As shown, this embodiment provides a specific implementation of a retractable and foldable laser positioning wooden stake hammer, including a sleeve 20 that can be movably fitted onto a wooden stake 30 and a folding hammer 10. When not in use, the folding hammer 10 can be housed in the sleeve 20. When in use, the folding hammer 10 intermittently strikes the top surface of the sleeve 20.

[0029] The laser emitter 107 and the crosshair 201 are provided. There are two laser emitters 107, which are symmetrically installed on both sides of the hammer head 101 of the folding hammer 10. The crosshair 201 is installed on the top surface of the sleeve 20 corresponding to the laser emitter 107.

[0030] In the above scheme, the laser emitter 107 is detachably fixed to both sides of the hammer head 101. The crosshair 201 is used to calibrate the cross-shaped beam emitted by the laser emitter 107, ensuring that the crosshair projected by the laser generator 107 remains vertical, ensuring that the hammer head hits the sleeve vertically, and avoiding hammering crookedly. It can be stored in the sleeve 20 to store the folding hammer 10, which is small in size and easy to carry.

[0031] The specific structure is as follows:

[0032] The folding hammer 10 includes a hammer head 101 and a mounting port 108 on the side of the hammer head 101; a hammer handle 102 is rotatably connected to the mounting port 108 via a universal joint 106; the universal joint 106 supports rotation from 0 to 90 degrees, and the hammer handle 102 is embedded in the hammer head 101 after folding.

[0033] Furthermore, the hammer handle 102 is a telescopic hammer handle.

[0034] Furthermore, the hammer handle 102 is composed of several support rods 109 and a knob locking ring 105. Adjacent support rods 109 are connected by a knob locking ring 105. The knob locking ring achieves the fastening and locking function through knob operation. Users can adjust the position of the locking ring by rotating the knob to achieve the locking effect. The length can be adjusted by the knob locking ring 105. The length of the hammer handle 102 is between 500mm and 1200mm to adapt to different working scenarios.

[0035] In one specific embodiment, the hammer handle 102 is made of aerospace aluminum alloy, which has a density that is only one-third that of steel, helping to reduce structural weight while also having good corrosion resistance.

[0036] In other embodiments, a spring pin 104 is installed on one side of the universal joint 106 to realize one-click locking of the hammer handle 102. It automatically locks when unfolded and enters the folded state after being pressed, changing the vertical or horizontal state of the hammer handle 102.

[0037] The sleeve 20 is a frustum-shaped cylinder with an open bottom end, and the inside of the sleeve 20 is hollow. The sleeve 20 enlarges the force-bearing surface for hammering, making it less likely to hit the hand and preventing the wooden stake from cracking.

[0038] Furthermore, an adjusting bolt 203 is installed on the bottom side of the sleeve 20 to fix the sleeve 20 and the wooden stake 30, which is compatible with 30-80mm wooden stakes 30.

[0039] In one specific embodiment, a shock-absorbing ring 202 is fixed to the top surface of the sleeve 20 to reduce the impact on the laser component when the folding hammer 10 strikes.

[0040] Furthermore, the shock-absorbing ring 202 is made of nylon material, which is a thermoplastic resin whose most prominent advantage is that its wear resistance is higher than that of all other fibers.

[0041] In other embodiments, the shock-absorbing ring 202 may include, but is not limited to, rubber material, as long as it is a wear-resistant material.

[0042] Specific operating method of this utility model:

[0043] Step 1: Preparation: Rotate to unlock hammer handle 102, stretch to the required length and tighten; press spring pin 104, rotate hammer head to vertical working position, spring pin 104 will lock automatically.

[0044] Step 2: Fixing the wooden stake 30: Insert the wooden stake 30 into the sleeve 20, move it vertically to the position where the wooden stake 30 will be buried, and hold the sleeve 20 with your left hand; turn on the laser emitter 107, hold the hammer handle 102 with your right hand to activate the laser, and adjust the hammer head 101 so that the crosshair is aligned with the sleeve.

[0045] Step 3: Striking operation: Hold the hammer handle 102 with your right hand and apply force vertically in the direction guided by the laser.

[0046] Step 4: Storage process: Unlock the telescopic locking ring of hammer handle 102 and retract hammer handle 102 to its shortest length; press spring pin 104 to rotate hammer handle 102 90 degrees so that hammer handle 102 is embedded in hammer head, and put hammer head 101 into sleeve.

[0047] In summary, the folding hammer 10 of this utility model is telescopic, with a folding hammer handle that can be embedded and stored. It is small in size and easy to carry. The sleeve fixes the wooden stake 30, ensuring that the wooden stake 30 is perpendicular to the ground. At the same time, the sleeve can also store the hammer head. Furthermore, the laser emitter 107 and the crosshair 201 work together to ensure that the hammer head strikes the sleeve perpendicularly. This not only achieves precise striking but also ensures safety. It can be widely used in any project that requires the installation of wooden stakes 30.
