[0012] As a preferred solution of the present invention, fixing frames are fixedly installed on both the left and right sides of the metal shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the handle is held by hand and pulled along the axial direction of the test rod. After the handle is pulled, it will drive the test rod to move along the inside of the guide hole. The movement of the test rod will also drive the connecting angle plate, the hinge pin, and the hinged connecting rod to move together. The movement of the hinged connecting rod will pull the output end of the tensile meter, so that the tensile force value is calculated by the tensile meter, and the tensile force data of the arm muscle strength tested by the tester are given.

[0014] 2. In the present invention, the torsion bracket is driven to rotate by moving the dial bar along the adjustment slot. The tester holds the handle and keeps the axis of the arm and the test rod on the same line. A lateral dial force is applied to the outer wall of the test rod, so that the test rod drives the turntable to twist along the top of the No. 1 positioning axis. The twisting of the test rod drives the output end of the tensile tester to move through the connecting action of the connecting angle plate, the hinge pin and the hinged connecting rod, so that the tensile force value is calculated by the tensile tester, and the dial force data of the arm muscle strength tested by the tester is given, thereby providing the tester with a full range of tests.

[0015] 3. In the present invention, when testing the tension of the tester's arm muscle strength, due to the thrust of the push cam on the top cap, the push column presses the pin tightly against the inside of the torque limiting slot, so that the turntable is limited in rotation, ensuring that the turntable will not twist during the tension test. That is to say, during the tension test, the axis of the test pull rod always remains in the same straight line with the tester's arm, ensuring the accuracy of the test.

[0016] 4. In the present invention, when the torsion bracket is rotated, the push cam is driven to rotate together, so that the push cam releases the thrust applied to the top cap, and the reset spring in the stretched state rebounds, pulling the push block together with the latch to move in the direction away from the torque limiting slot, so that the latch is withdrawn from the inside of the torque limiting slot, and the torque limit of the turntable is released. In this way, the free torsion of the turntable can be guaranteed, and the turning force test is convenient. During the movement of the latch in the direction away from the torque limiting slot, the wedge force block is also driven to move together, pushing the guide wheel upward. The upward movement of the guide wheel further drives the positioning lock column together with the positioning lock core to move together, so that the positioning lock core is inserted into the inside of the limiting slide groove, and the test pull rod is positioned inside the guide hole and cannot move, thereby ensuring that the test pull rod will not move inside the guide hole during the turning force test, thereby improving the accuracy of the turning force test.

An adjustment groove 102 is provided on a side of the metal shell 100 close to the tensile gauge 207, and the lever 2013 is movably located inside the adjustment groove 102.

[0022] Specifically, the tester is fixed by a fixing frame 400 disposed around the metal housing 100 to ensure the stability of the tester. The tester can test the pulling force and pulling force of the arm muscle strength of the tester, as follows: When testing the tensile force data of the arm muscle strength, the tester holds the handle 2014 and pulls the handle 2014 along the axial direction of the test rod 204. After the handle 2014 is pulled, it drives the test rod 204 to move along the inside of the guide hole 203. The movement of the test rod 204 also drives the connecting angle plate 209, the hinge pin 2010, and the hinge connecting rod 208 to move together. The movement of the hinge connecting rod 208 pulls the output end of the tensile meter 207, so that the tensile force value is calculated by the tensile meter 207, and the tensile force data of the arm muscle strength tested by the tester is given; When testing the pulling force data of the arm muscle strength, firstly, the locking frame 2011 is screwed upwards through the threaded action, so that the bottom of the screw cap of the fastening bolt 2012 is separated from the top of the metal shell 100. At this time, force can be applied to the surface of the pull bar 2013 to pull the torsion bracket 206 along the outer wall of the second positioning shaft 205 to rotate 90 degrees. During this period, the fastening bolt 2012 moves along the arc groove 101, and the pull bar 2013 moves along the adjustment groove 102. When the torsion bracket 206 rotates 90 degrees, the fastening bolt 2012 is tightened again so that the bottom of the screw cap abuts against the top of the metal shell 100, thereby limiting the locking frame 2011, that is, positioning the torsion bracket 206 to avoid The rotated torsion bracket 206 rotates again. After the torsion bracket 206 is positioned, the tester holds the handle 2014 and keeps the arm and the axis of the test rod 204 on the same line. A lateral pushing force is applied to the outer wall of the test rod 204, so that the test rod 204 drives the turntable 202 to twist along the top of the No. 1 positioning axis 201. The twisting of the test rod 204 drives the output end of the tensile meter 207 to move through the connection of the connecting angle plate 209, the hinge pin 2010 and the hinge connecting rod 208, so that the tension value is calculated by the tensile meter 207, and the pushing force data of the arm muscle strength tested by the tester is given, thereby providing a full range of tests for the tester.

[0023] For further details, please refer to Figure 3 to Figure 8 As shown: The positioning components include a limited slide groove 301, a limit plate 302, a torque limit slot 303, a guide frame plate 304, a latch 307, a top column 308, a top cap 309, a push cam 3010, a positioning lock column 3012, a positioning lock core 3013, a U-shaped groove 3014, a guide wheel 3015, a push block 3018, a spring fixing seat 3019 and a reset spring 3020. The limited slide groove 301 is provided on the outer wall of the test pull rod 204 and is close to one end of the connecting angle plate 209. The limit plate 302 is fixedly mounted on the outer wall of the No. 1 positioning shaft 201. The limit plate 302 is located at the bottom of the turntable 202, and a limited torque slot 303 is provided on the side of the outer wall of the limit plate 302 close to the second positioning shaft 205. The guide frame plate 304 is fixedly installed on the outer wall of the turntable 202 and close to the side of the second positioning shaft 205. There are two guide frame plates 304, and the two guide frame plates 304 are symmetrically distributed about the central axis of the turntable 202. The latch 307 is slidably arranged between the two guide frame plates 304, and the end of the latch 307 is inserted into the inner part of the limited torque slot 303. The top column 308 is fixedly installed on the latch 307 away from the limited torque slot. The top cap 309 is fixedly mounted on one side of the slot 303, the top cap 309 is fixedly mounted on the end of the top column 308 away from the latch 307, the top push cam 3010 is fixedly mounted on the top of the torsion bracket 206 and close to the side of the limit plate 302, the top push cam 3010 abuts against the top cap 309, the wedge block 3011 is fixedly mounted on the top of the latch 307, the positioning lock column 3012 is slidably set between the two guide frame plates 304, the positioning lock core 3013 is fixedly mounted on the top of the positioning lock column 3012, and the position and specification of the positioning lock core 3013 are consistent with the position and specification of the limit slide slot 301. The grids are adapted to each other, a U-shaped groove 3014 is provided at the bottom of the positioning lock cylinder 3013, a guide wheel 3015 is rotatably installed inside the U-shaped groove 3014, the bottom of the guide wheel 3015 contacts the bottom of the latch 307, the guide wheel 3015 is located on the side of the wedge block 3011, the push block 3018 is fixedly installed on the top of the latch 307, the spring fixing seat 3019 is fixedly installed between the two guide frame plates 304, and close to one end of the second positioning shaft 205, and the reset spring 3020 is fixedly installed between the push block 3018 and the spring fixing seat 3019.

[0024] Specifically, when testing the tensile force of the test subject's arm muscle strength, due to the thrust of the push cam 3010 on the top cap 309, the top column 308 presses the pin 307 tightly against the inside of the torque limiting slot 303, so that the turntable 202 is limited in rotation, ensuring that the turntable 202 will not twist during the tensile test. In other words, during the tensile test, the axis of the test pull rod 204 always remains in the same straight line with the test subject's arm to ensure the accuracy of the test. When a toggle force test is required, when the torsion bracket 206 is rotated, the push cam 3010 will be driven to rotate together, so that the push cam 3010 releases the thrust applied to the top cap 309, and the reset spring 3020 in the stretched state rebounds, pulling the push block 3018 together with the pin 30 7 moves in the direction away from the torque limiting slot 303, so that the pin 307 withdraws from the inside of the torque limiting slot 303, and the torque limiting of the turntable 202 is released. In this way, the free rotation of the turntable 202 can be guaranteed, and the turning force test is convenient. During the movement of the pin 307 in the direction away from the torque limiting slot 303, the wedge block 3011 is also driven to move, and the guide wheel 3015 is pushed upward. The upward movement of the guide wheel 3015 further drives the positioning lock column 3012 together with the positioning lock core 3013 to move, so that the positioning lock core 3013 is inserted into the inside of the sliding limit slot 301, and the test rod 204 is positioned inside the guide hole 203 and cannot move, ensuring that the test rod 204 will not move inside the guide hole 203 during the turning force test, and the accuracy of the turning force test can be improved.

[0025] For further details, please refer to Figure 5 and Figure 8 As shown: The test component also includes a No. 1 path groove 305, a No. 2 wheel diameter groove 306, a No. 1 guide strip 3016 and a No. 2 guide strip 3017. The No. 1 path groove 305 is vertically arranged and opened on the opposite surfaces of the two guide frame plates 304. The No. 2 guide strip 3017 is fixedly installed on the two side surfaces of the positioning lock column 3012 close to the two guide frame plates 304, and the No. 2 guide strip 3017 is slidably connected to the inside of the No. 1 path groove 305. The No. 2 wheel diameter groove 306 is horizontally arranged and opened on the opposite surfaces of the two guide frame plates 304. The No. 1 guide strip 3016 is fixedly installed on the two side surfaces of the latch 307 close to the two guide frame plates 304, and the No. 1 guide strip 3016 is slidably connected to the inside of the No. 2 wheel diameter groove 306.

[0026] Specifically, by setting the sliding connection between the No. 1 guide strip 3016 and the No. 2 wheel diameter groove 306, a precise sliding guiding effect can be provided to the pin 307, so that the pin 307 can be accurately inserted into the interior of the torque limiting groove 303, thereby providing a good torque limiting effect to the turntable 202. By setting the sliding connection between the No. 2 guide strip 3017 and the No. 1 path groove 305, a precise sliding guiding effect can be provided to the U-shaped groove 3014, so that the positioning lock core 3013 can be accurately inserted into the interior of the sliding limiting groove 301, and a precise limiting effect can be provided to the test rod 204, so that the test rod 204 can be positioned inside the guide hole 203 to prevent it from sliding.

[0027] When the muscle strength all-round tester of this scheme is working, the tester is fixed by the fixing frame 400 arranged around the metal shell 100 to ensure the stability of the tester. The tester can test the pulling force and pulling force of the arm muscle strength of the tester, as follows: When testing the tensile force data of the arm muscle strength, the tester holds the handle 2014 and pulls the handle 2014 along the axial direction of the test rod 204. After the handle 2014 is pulled, it drives the test rod 204 to move along the inside of the guide hole 203. The movement of the test rod 204 also drives the connecting angle plate 209, the hinge pin 2010, and the hinge connecting rod 208 to move together. The movement of the hinge connecting rod 208 pulls the output end of the tensile meter 207, so that the tensile force value is calculated by the tensile meter 207, and the tensile force data of the arm muscle strength tested by the tester is given; When testing the pulling force data of the arm muscle strength, firstly, the locking frame 2011 is screwed upwards through the threaded action, so that the bottom of the screw cap of the fastening bolt 2012 is separated from the top of the metal shell 100. At this time, force can be applied to the surface of the pull bar 2013 to pull the torsion bracket 206 along the outer wall of the second positioning shaft 205 to rotate 90 degrees. During this period, the fastening bolt 2012 moves along the arc groove 101, and the pull bar 2013 moves along the adjustment groove 102. When the torsion bracket 206 rotates 90 degrees, the fastening bolt 2012 is tightened again so that the bottom of the screw cap abuts against the top of the metal shell 100, thereby limiting the locking frame 2011, that is, positioning the torsion bracket 206 to avoid The rotated torsion bracket 206 rotates again. After the positioning of the torsion bracket 206 is completed, the tester holds the handle 2014 and keeps the arm and the axis of the test rod 204 on the same line, and applies a lateral pushing force to the outer wall of the test rod 204, so that the test rod 204 drives the turntable 202 to twist along the top of the No. 1 positioning axis 201. The twisting of the test rod 204 drives the output end of the tensile meter 207 to move through the connection of the connecting angle plate 209, the hinge pin 2010 and the hinge connecting rod 208, so that the tensile force value is calculated by the tensile meter 207, and the pushing force data of the arm muscle strength tested by the tester is given, thereby providing a full range of tests for the tester; It should be noted that when testing the tensile force of the tester's arm muscle strength, due to the thrust of the push cam 3010 on the top cap 309, the top column 308 presses the pin 307 tightly against the inside of the torque limiting slot 303, so that the turntable 202 is limited in rotation, ensuring that the turntable 202 will not twist during the tensile test. In other words, during the tensile test, the axis of the test pull rod 204 always remains in the same straight line with the tester's arm to ensure the accuracy of the test. When a toggle force test is required, when the torsion bracket 206 is rotated, the push cam 3010 will be driven to rotate together, so that the push cam 3010 releases the thrust applied to the top cap 309, and the reset spring 3020 in the stretched state rebounds, pulling the push block 3018 together with the pin 307. 07 moves in the direction away from the torque limiting slot 303, so that the pin 307 withdraws from the inside of the torque limiting slot 303, and the torque limit on the turntable 202 is released. In this way, the free twisting of the turntable 202 is guaranteed, which is convenient for the toggle force test. During the movement of the pin 307 in the direction away from the torque limiting slot 303, the wedge block 3011 is also driven to move, pushing the guide wheel 3015 upward. The upward movement of the guide wheel 3015 further drives the positioning lock column 3012 together with the positioning lock core 3013 to move, so that the positioning lock core 3013 is inserted into the inside of the limiting slide slot 301, and the test rod 204 is positioned inside the guide hole 203 and cannot move, ensuring that during the toggle force test, the test rod 204 will not move inside the guide hole 203, which can improve the accuracy of the toggle force test.

[0028] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
