[0027] Example 1

[0028] Reference Figures 1 to 4 , which is the first embodiment of the present utility model, provides a concrete rebound test hammer, which includes an external component 100 and a support component 200, wherein the external component 100 includes a rod body 101, a weight 102 arranged in the rod body 101, and a display 103 arranged on the rod body 101; the support component 200 is arranged on the rod body 101, and includes a handle 201 arranged at the end of the rod body 101, a connecting port 202 arranged on the rod body 101, a return spring 203 arranged in the connecting port 202, a clamping plate 204 connected to the return spring 203, a slide groove 205 and a notch 206 arranged in the connecting port 202, a grip 207 arranged on the connecting port 202, and a protrusion 208 provided on the grip 207.

[0029] The weight 102 is slidably connected to the shaft 101, and the display 103 shows the reading returned by the weight 102. The handle 201 is rotatably connected to the end of the shaft 101. The connecting port 202 is provided on the shaft 101, and a reset chamber 202a is provided within the connecting port 202. The reset spring 203 and the clamping plate 204 are disposed within the reset chamber 202a. One end of the reset spring 203 is connected to the inner wall of the reset chamber 202a, and the other end is fixedly connected to the clamping plate 204. The reset spring 203 is naturally compressed. The clamping plate 204 is annular, and the radial diameter of the inner wall of the clamping plate 204 is the same as the radial diameter of the inner wall of the connecting port 202. The chute 205 is symmetrically arranged on the inner wall of the connecting port 202. The chute 205 is linear and connects from the end of the connecting port 202 to the reset chamber 202a. The notches 206 are symmetrically arranged within the reset cavity 202a, interlaced with the slots 205. The handle 207 is cylindrical and slidably connected to the connection port 202. The sidewalls of the handle 207 are symmetrically provided with protrusions 208. The protrusions 208 can be inserted into the slots 205 or the notches 206.

[0030] During use, align the weight 102 with the point to be measured and push the shaft 101 to read the value on the display 103. This is a conventional operation for reading the rebound hammer and will not be described in detail here. In order to increase the gripping point on the rebound hammer shaft 101, a handle 201 is provided at the end of the shaft 101. Align the protrusion 208 on the handle 207 with the slide groove 205 and insert the handle 207 into the connection port 202. When the protrusion 208 enters the reset cavity 202a, continue to insert the handle 207 and push the card plate 204 to compress the reset spring 203. Turn the handle 207 to make the protrusion 208 leave the slide groove 205, turn the protrusion 208 to the notch 206, release the handle 207, the reset spring 203 resets, pushes the card plate 204, and the card plate 204 squeezes the protrusion 208 into the notch 206. At this time, the fixed connection between the handle 207 and the connecting port 202 can be completed. The operator can hold the handle 201 and the handle 207 to improve the stability of the heavy hammer 102 during squeezing. After the measurement is completed, the above steps can be reversed to remove the handle 207 from the connecting port 202 for easy carrying.
