[0014] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0015] like Figure 1-3 As shown, a handheld positioning mechanism for detecting the installation accuracy of a back door comprises a fixing mechanism 1, a positioning mechanism 2 and a fetal membrane 3, wherein the fixing mechanism is connected to the fetal membrane through the positioning mechanism. The mechanism is fixed to the vehicle body by opening and clamping a hook pin mechanism driven by a quick card fixed on a connecting plate, and the mechanism is smoothly fixed to the vehicle body, and the gap tolerance between the fetal membrane and the vehicle body is detected to confirm whether the installation of the back door meets the accuracy requirements.

[0016] The fixing mechanism is composed of two sets, including a quick card 11 and a connecting plate 12, wherein the quick card is connected to one end of the connecting plate, and the other end of the connecting plate is connected to the fetal membrane. The shape of the connecting plate in the device can be set according to the specific vehicle model, and its main purpose is to fix the quick card. The connecting plate in the device is designed into two structures according to the positioning mechanism. One is to directly fix the quick card on the fetal membrane, and the other structure is to design the connecting plate into two separate parts, which also fixes the quick card on the fetal membrane.

[0017] In the present device, there are two sets of positioning mechanisms, and the structures of the two sets of positioning mechanisms are the same, except that the outermost connecting parts are different, one is connected to the fetal membrane, and the other is connected to the connecting plate, and the directions of the two sets of positioning mechanisms are consistent. The two sets of positioning mechanisms correspond to the quick-card connection in the fixing mechanism respectively. The positioning mechanism includes a positioning pin 21, a hook pin 22, a pin seat 23, a sleeve 24, a sliding sleeve 25 and a sleeve 26. The positioning pin is fixed at one end of the pin seat, and the pin seat is fixed at one end of the sleeve. There is a through hole between the pin seat and the positioning pin, and the hook pin passes through the through hole. The other end of the hook pin is slidably connected with the inside of the sliding sleeve. A pin shaft 27 is provided on the sliding sleeve, and a guide groove 28 is provided on the body of the hook pin, and the guide groove cooperates with the pin shaft. The other end of the hook pin is connected to a movable rod 29 through a pin shaft 210. A guide sleeve 20 is provided outside the movable rod, and the guide sleeve is connected to a sliding rod on the inner wall of the sliding sleeve. The sleeve is fixed at the other end of the sliding sleeve, and the movable rod passes through the sleeve, and the other end of the movable rod is connected to the movable end of the quick card. The locating pin corresponds to the through hole of the door to be inspected. The locating pin can be inserted into the through hole on the door. Then, by pulling the quick card, the quick card drives the hook pin to move in the sliding sleeve through the movable rod. Since the hook pin is provided with a guide groove, the guide groove moves along the pin shaft, and the front end of the hook pin extends out to hook the door, thereby fixing the entire device to the door, and the assembly accuracy of the back door is inspected through the fetal membrane.

[0018] In order to facilitate the movement of the entire device, a handle 4 is provided on the connecting plate.

[0019] After the whole mechanism is assembled, the positioning pin is inserted into the positioning hole of the car back door, and the quick clamp is operated to fix it on the back door. The assembly accuracy of the back door is tested by measuring the tolerance between the fetal membrane and the side of the car.

[0020] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
