The bottom of the inner wall of the connecting column 601 is slidably connected with a pressing plate 602, and an air pressure bag is installed at the bottom of the pressing plate 602. When the pressing plate 602 slides inward into the interior of the connecting column 601, it squeezes the air pressure bag, thereby generating air pressure to flow into the drainage rod 6055. A telescopic cavity 603 is provided at the top of the connecting column 601, and a covering component 605 is provided on the inner wall of the telescopic cavity 603. The inner wall of the connecting column 601 is provided with a compression component 604.

[0023] The compression assembly 604 includes a pad 6041 fixedly connected to the inner wall of the wrapping column 601, a telescopic rod 6042 is slidably connected to the top slot of the pad 6041, a covering block 6044 is fixedly connected to the top of the telescopic rod 6042, a plug-in tube 6043 is fixedly connected to the top of the covering block 6044, a clip 6045 is fixedly connected to the top of the covering block 6044, and the plug-in tube 6043 is arranged at the centers of both sides of the clip 6045.

[0024] The covering assembly 605 includes a covering film 6051 fixedly connected to the inner wall of the telescopic cavity 603, and one end of the covering film 6051 is connected to one end of the compression column 6056 inside the spray block 6054. When the compression column 6056 slides outward, it will drive one end of the covering film 6051 to slide inside the spray block 6054. The top of the covering column 601 is fixedly connected to the spray block 6054, and the end of the covering film 6051 away from the telescopic cavity 6003 is slidably connected to the inner wall of the spray block 6054. The right side of the spray block 6054 is fixedly connected to the drainage rod 6055, and the end of the drainage rod 6055 away from the spray block 6054 is fixedly connected to the top of the covering column 601. The right side of the spray block 6054 is fixedly connected to the compression column 6056, and the end of the compression column 6056 away from the spray block 6054 is slidably connected to the surface slot of the beam 5.

[0025] The working method of the first embodiment is as follows: first, the mounting frame 2 is fixedly installed on the horizontal bar. When the person being tested does pull-ups, the person's hands will hold the inner wall of the enveloping column 601. When the fingers hold the inner wall of the enveloping column 601, the fingers press the pressing plate 602, thereby squeezing the pressing plate 602 so that one end of the pressing plate 602 is stretched and retracted inside the enveloping column 601. When the pressing plate 602 stretches and retracts inward, air pressure is generated and flows into the interior of the spray block 6054 through the guide rod 6055. The air pressure flowing into the interior of the spray block 6054 pushes the compression column 6056, so that one end of the compression column 6056 stretches and retracts from the interior of the spray block 6054 to the surface slot of the crossbeam 5. When the compression column 6056 stretches and retracts inward, the compression column 6056 is pushed. When it expands and contracts outward, it will drive one end of the covering film 6051 to slide toward the inside of the spray block 6054. When the covering film 6051 expands and contracts inward, it will come into contact with the hand of the person being tested. After the plug-in column 6052 is inserted into the inside of the plug-in tube 6043, the covering film 6051 will be fixed to the inner wall of the plug-in tube 6043. The covering film 6051 will wrap the hand of the person being tested, thereby fixing the hand of the person being tested to the inner wall of the covering column 601. By setting up this mechanism, it can be used to fix the hands of different persons being tested, so that the palms of the persons being tested can better grip the covering column 601, prevent the palms from sweating and being unable to better fix the covering column 601, thereby making it impossible for the persons being tested to complete pull-ups efficiently.

[0026] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6 The storage mechanism 7 includes an import block 701, which is fixedly connected to the bottom of the beam 5. The left side of the import block 701 is fixedly connected to a storage tank 703, the left side of the import block 701 is fixedly connected to a connecting disk 702, the inner wall of the connecting disk 702 is fixedly connected to an air duct rod 704, and the end of the air duct rod 704 away from the connecting disk 702 is provided with a telescopic component 705, and the right side of the connecting disk 702 is provided with a counting component 706.

[0027] The telescopic assembly 705 includes a covering shell 7051, which is fixedly connected to the bottom of the covering column 601. A compression rod 7052 is slidably connected to the bottom slot of the covering column 601. A pushing tube 7053 is fixedly connected to the bottom of the compression rod 7052. The end of the pushing tube 7053 away from the compression rod 7052 is fixedly connected to a wrapping ball 7054. The interior of the wrapping ball 7054 is filled with compressed gas. When the inner wall of the wrapping ball 7054 is pushed by one end of the pushing tube 7053, the compressed gas inside it will be discharged outward. The end of the air duct 704 away from the connecting disk 702 is fixedly connected to the surface of the wrapping ball 7054.

[0028] The counting component 706 includes a flow chamber 7061, one end of which is fixedly connected to the right side of the import block 701, a flow rod 7062 is fixedly connected to the bottom of the inner wall of the import block 701, and a telescopic pad 7064 is fixedly connected to the end of the flow rod 7062 away from the import block 701.

[0029] The counting assembly 706 also includes a counting ball 7063, which is slidably connected to the surface of the flow rod 7062, and a plurality of counting balls 7063 are stored in the storage tank 703. When the compressed gas enters the inside of the introduction block 701, it pushes the counting ball 7063, and each compressed gas generated in the wrapping ball 7054 pushes a counting ball 7063 in the introduction block 701, so that one of the counting balls 7063 slides on the surface of the flow rod 7062. The bottom of the telescopic pad 7064 is fixedly connected to the chassis 7065, the top of the chassis 7065 is fixedly connected to the bell ball 7066, the surface of the chassis 7065 is fixedly connected to the side plate 7067, and the inner walls of the side plate 7067 are rotatably connected to counting blocks 7068 on both sides. The inside of the counting block 7068 is engraved with digital marks. When one end of the counting block 7068 is pushed, it will rotate on the inner wall of the side plate 7067, thereby driving one end of the counting block 7068 to tilt upward and reveal the digital mark.

[0030] The working method of the second embodiment is as follows: when the examinee holds the inner wall of the enveloping column 601 with his hands, the examinee's two fingers will press the inside of the clip 6045. When the examinee performs pull-ups, the examinee's fingers will press the top of the enveloping block 6044, so that the telescopic rod 6042 at the bottom of the enveloping block 6044 is pressurized and slides downward inside the pad 6041. When the telescopic rod 6042 slides downward, it will be extended and retracted inside the enveloping column 601. When the telescopic rod 6042 is extended and retracted downward to the surface of the compression rod 7052, one end of the telescopic rod 6042 squeezes the surface of the compression rod 7052, so that one end of the compression rod 7052 is pressed against the enveloping shell 70 51 slides on the inner wall. When one end of the compression rod 7052 squeezes the top of the pushing tube 7053, it drives the pushing tube 7053 to expand and contract inward and generates pressure on the inside of the wrapped ball 7054, so that the compressed gas inside the wrapped ball 7054 is discharged into the introduction block 701 through the air guide rod 704. Every pull-up movement made by the person being tested will press the covering block 6044, which will drive one end of the telescopic rod 6042 to squeeze the surface of the compression rod 7052, so that the inside of the wrapped ball 7054 is pressurized and a stream of compressed gas enters the introduction block 701. When the counting ball 7063 slides toward the telescopic pad 7054 through the flow rod 7062, 64, pressure is generated on the top of the telescopic pad 7064, causing the telescopic pad 7064 to telescope inward, thereby allowing the counting ball 7063 to come into contact with the surface of the counting block 7068, causing one end of the counting block 7068 to tilt upward from the inner wall of the side plate 7067, and the surface of the counting block 7068 is engraved with digital marks, so the number of pull-ups done by the examinee can be counted by observing the digital marks on the surface of the counting block 7068 without the staff having to observe the number of pull-ups done by the examinee. When the counting ball 7063 slides toward the top of the telescopic pad 7064 through the flow rod 7062, the top of the telescopic pad 7064 will be subjected to pressure and telescope inward. When the top of the telescopic pad 7064 is subjected to the pressure brought by multiple counting balls 7063, the compression pad at the bottom of the telescopic pad 7064 will be compressed inward due to the pressure. When the number of counting balls 7063 on the top of the telescopic pad 7064 reaches the standard, the compression pad at the bottom of the telescopic pad 7064 will be extended inward to the top of the ringing ball 7066, and the top of the ringing ball 7066 will be squeezed through the bottom of the telescopic pad 7064, so that the inside of the ringing ball 7066 will produce a crisp metal collision sound due to the squeezing. When the number of pull-ups done by the person being tested reaches the standard, the ringing ball 7066 will be made to make a sound, thereby reminding the staff that the person being tested has reached the standard.

[0031] Example 3: Based on Example 1, continue to refer to Figure 7-Figure 8The dissipation component 8 includes a cooling tank 801, which is fixedly connected to the top of the crossbeam 5. The two sides of the cooling tank 801 are fixedly connected with an air inlet pipe 802. Condensed gas is injected into the cooling tank 801. When the inside of the cooling tank 801 is squeezed by compressed gas, the condensed gas will be compressed and discharged outward. The two sides of the cooling tank 801 are fixedly connected with an air inlet cavity 803. The air inlet cavity 803 is fixedly connected to the top of the crossbeam 5. The top of the air inlet cavity 803 is fixedly connected with a flow block 804.

[0032] The dispersing component 8 also includes a wrapping block 805, which is fixedly connected to one end of the flow block 804. The inner wall of the wrapping block 805 is slidably connected to an air pressure belt 806. The end of the air pressure belt 806 away from the inner wall of the wrapping block 805 is fixedly connected to the inner wall of the coating film 6051, and the end of the air inlet pipe 802 away from the cooling tank 801 is fixedly connected to the top of the flow block 804.

[0033] The working method of the third embodiment is as follows: when one end of the compression column 6056 is extended and retracted toward the surface slot of the beam 5, the air pressure membrane inside the beam 5 is squeezed, so that the air pressure inside the air pressure membrane is generated and flows into the cooling tank 801 through the air inlet cavity 803, and the condensed gas inside the cooling tank 801 is compressed by the air pressure, so that the condensed gas inside the cooling tank 801 is compressed and discharged outward through the air inlet pipe 802, and the discharged condensed gas enters the interior of the flow block 804, thereby discharging the condensed gas into the air pressure belt 806 through the flow block 804, and the condensed gas is poured into the covering through the internal cavity of the air pressure belt 806. Inside the membrane 6051, when the condensed gas passes through the internal membrane cavity of the coating membrane 6051, it will flow into the interior of the jet block 6053 and be ejected outward through the jet holes on both sides of the jet block 6053. The two sides of the jet block 6053 will contact each other at the gaps between the fingers, so the condensed gas ejected outward through the jet block 6053 will be sprayed toward the gaps between the fingers and the surface of the palm. When the person being tested does pull-ups, the sweat generated by the friction between the palm and the wrapping column 601 will be cooled and evaporated by the condensed gas, which can indirectly improve the test efficiency of the person being tested when doing pull-ups and avoid affecting the test efficiency due to the person being tested's hands slipping during the test.
