[0002] As a representative product of hardware tools, hammers have been widely used in life or related work. With the increasing sales of hammers in global trade, countries are paying more and more attention to the safety of such products. Hammers, which are composed of a hammer head and a handle, are simple in structure and serve as a tool for people to knock objects to move or deform them. The weight of the hammer should be adapted to the workpiece, material and action, and too heavy or too light will be unsafe. Injury cases caused by quality problems also occur from time to time. Before leaving the factory, the hammer needs to be tested for basic safety performance to verify whether the hammer head or handle is deformed or cracked after being struck, whether the handle and hammer head are loose, and whether the handle is bent or broken under stress during high-intensity use.

[0003] The traditional bending resistance test method for hammers is to use a bending resistance test device to fix the hammer head at one end of the hammer with a stopper, and to suspend the hammer handle at the other end and directly use a lifting structure for pressure testing. However, the existing test device cannot limit and fix the hammer, and manual assistance is required for fixing. During the test, the hammer is prone to deviation under stress, affecting the accuracy of the test. Not only is the operation difficult, but also the cost is high, and there are safety hazards in work. Moreover, the existing test device can only test the bending strength of the connection between the handle and the hammer head or the bending strength of the handle itself, which requires a large investment in equipment and is complicated to operate, and the test efficiency is low.

[0072] As shown in Figure 2 、 Figure 5 、 Figure 6 and Figure 9 , in order to avoid displacement or tilting of the test table 300 during the test, the bottom of the test table 300 is fixed on the support base 100 by the connecting column 340. The connecting column 340 is at least one and is arranged at the bottom of the base seat 320, is respectively inserted into the mounting hole 101 at the top of the left end of the support base 100, and is locked and fixed by a nut from the bottom of the support base 100.

[0073] In some embodiments, as shown in Figure 8 、 Figure 10 and Figure 12 , in order to realize the limiting and fixing of the tool seat 400 and avoid rotation of the tool seat 400 during the test, causing the hammer 700 to be tested to be offset. A square clamping groove 322 is formed at the top of the base seat 320 corresponding to the position of the cylindrical groove 321, and a plurality of first limiting columns 323 are arranged in the square clamping groove 322. The first limiting column 323 is inserted into the first limiting groove 421 at the bottom of the square clamping block 420, thereby realizing the limiting and fixing of the tool seat 400.

[0074] In addition, according to the need, a plurality of second limiting columns 324 are arranged at the bottom of the cylindrical groove 321, and a downward penetrating insertion hole 325 is formed at the center position. The second limiting column 324 is inserted into the second limiting groove 413 arranged at the bottom of the work position groove 410, and cooperates with the first limiting column 323 above, thereby ensuring the stability of the installation of the tool seat 400 in the cylindrical groove 321 from top to bottom.

[0075] In some embodiments, as shown in Figure 8 、 Figure 9 and Figure 10 , the hammer head locking mechanism 330 mainly comprises a supporting column 331, a pressing rod 333, a first locking screw 334 and a bottom baffle 335, which is used for pressing the pressing rod 333 onto the hammer head by rotating the first locking screw 334, thereby achieving the purpose of fixing the hammer head.

[0076] Specifically, the support column 331 is two, respectively arranged at both sides of the lower end of the cylindrical groove 321, and a square adjusting hole 332 is formed on the upper end of each support column 331; the two ends of the pressing rod 333 are movably arranged in the square adjusting hole 332 at both ends, and the end portion is in abutting connection with the first locking screw 334 screwed on the top of the support column 331; the bottom baffle 335 is arranged at the bottom of the two support columns 331, and is connected with the bottom end of the base seat 320 as an integral structure.

[0077] In use, the tip of the hammer head of the hammer 700 to be tested is inserted into the inside of the pressing rod 333 from the bottom of the pressing rod 333, the bottom of the hammer head is located in the hammer head groove 411, and the hammer handle is pressed into the work station groove 410. After the hammer 700 to be tested is placed in position, the first locking screw 334 is manually rotated, one end of the first locking screw 334 pushes the pressing rod 333 to tightly abut against the inside of the hammer head, and the feeding stroke is set to a certain distance from the bottom of the hammer handle to the bottom of the work station groove 410, so that the hammer head is fixed in position. After the test is completed, the first locking screw 334 is manually rotated in the opposite direction, and the hammer 700 to be tested is taken out.

[0078] In some embodiments, as shown in Figure 13 and Figure 14 , a plurality of work station grooves 410 are arranged on the circumferential body of the tool holder 400.
