[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, when the laser head assembly is removed from the mounting bracket on the laser base, the two handles at the rear of the mounting bracket are pushed, so that the two handles respectively drive the two side plates away from each other, so that the side plates drive the card blocks to slide in the grooves in the mounting bracket through the fixed columns, and then the two card blocks are respectively disengaged from the card slots on the sides of the laser head assembly, thereby releasing the locking state between the laser head assembly and the mounting bracket, and then the sliding rod is driven to move by the pulling force of the second spring, so that the multiple sliding rods can push the laser head assembly through the top plate, and then the top plate can pop out the laser head assembly, so that the card blocks are misaligned with the card slots in the mounting bracket to prevent the card blocks from being stuck in the card slots again when the handles are released, and then the laser head assembly is pulled out to disengage its ends from the card holes and through holes, so as to facilitate the removal of the laser head assembly, and when installing the laser head assembly, the laser head assembly is set up on the mounting bracket. In the frame, the laser head assembly is pushed so that the two blocks can be squeezed. Because the side of the block close to the laser head assembly is inclined, the blocks can move away from each other and move into the groove after being pressed, so as to prevent the blocks from being unable to move and interfering with the installation of the laser head assembly. Secondly, the end of the laser head assembly passes through the through hole and the card hole and squeezes the top plate. When the laser head assembly no longer moves, the block is supported by the elastic force of the first spring, so that the fixed column drives the block to be stuck in the card slot on the side of the laser head assembly, so as to achieve the purpose of locking the laser head assembly. Therefore, by independently designing the laser base and the laser head assembly, and adopting a card-type installation method for disassembly and assembly, the laser base and the laser head assembly can be quickly separated, reducing the difficulty of disassembly and assembly, which is beneficial to the maintenance of the Raman laser and the replacement of components.

[0015] 2. In the present invention, when the focus of the light source of the laser head assembly is adjusted, the fastening bolts on one side of the mounting frame can be loosened during the horizontal adjustment process to disengage the fastening bolts from the slide rail on one side of the laser base, so that the mounting frame and the laser head assembly are in a free movable state in the horizontal direction. The mounting frame is pushed to make the slider and the slide seat slide on the slideway and the slide rail respectively, which plays a role in limiting the horizontal position of the mounting frame and improving the movement stability of the laser head assembly. After the adjustment work is completed, the fastening bolts are tightened to make it contact with the slide rail, so that the mounting frame can be locked, thereby improving the working stability of the laser head assembly. During the process of adjusting the source focus, the handle can be rotated to drive the screw to rotate inside the two shaft sleeves. During the rotation of the screw, the nut outside the screw can drive the mounting frame to slide in the sliding hole. The mounting frame is limited by the sliding hole, thereby improving the stability of the mounting frame driving the laser head assembly to move. Since the laser head assembly can move on the mounting frame, the focus of the light source emitted by the laser head assembly can be adjusted, abandoning the traditional method of adjusting the position of the laser as a whole. The adjustment method in the present invention can ensure that the focus adjustment can be performed without moving the laser base, thereby improving the convenience of operation and the adjustment accuracy.

[0016] 3. In the present invention, when the connection state between the connecting wire and the laser head assembly is released, the threaded sleeve is rotated in the opposite direction to rotate on the external thread outside the socket, so that the threaded sleeve can be separated from the socket, that is, the threaded sleeve drives the guide column away from the socket through the sealing bearing until the connection terminal at the end of the guide column is separated from the socket, so that the connecting wire and the laser head assembly are disconnected, which is convenient for the subsequent disassembly and assembly of the laser head assembly. When using the laser head assembly, the connection terminal is inserted into the socket, and the threaded sleeve is rotated when the threaded sleeve contacts the socket, so that the threaded sleeve can be threadedly connected to the outside of the socket. Because the threaded sleeve is connected to the guide column through the sealing bearing, the guide column and the connection terminal will not rotate synchronously during the rotation of the threaded sleeve, so that the connection terminal is stuck in the socket without rotating, thereby improving the connection stability between the connection terminal and the socket. Secondly, a sealing ring is installed between the inner wall of the threaded sleeve and the socket. During the movement of the threaded sleeve outside the socket, the socket can be squeezed by the sealing ring, thereby improving the sealing connection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A slide rail 15 is provided on one side of the laser base 1, and a slide seat 403 is slidably connected to the slide rail 15, and both the slide rail 15 and the slide seat 403 are of trapezoidal design.

Loosen the fastening bolt 404 on one side of the mounting frame 3 to disengage the fastening bolt 404 from the slide rail 15 on one side of the laser base 1, so that the mounting frame 3 and the laser head assembly 2 are in a free movable state in the horizontal direction, tighten the fastening bolt 404 to make it contact with the slide rail 15, so that the mounting frame 3 can be locked, thereby improving the working stability of the laser head assembly 2.

[0029] An adjusting assembly 5 is installed in the sliding assembly 4, and the adjusting assembly 5 is fixed to the bottom of the mounting frame 3. The adjusting assembly 5 includes a screw rod 501, and shaft sleeves 502 are respectively sleeved on both sides of the screw rod 501. The two shaft sleeves 502 are respectively clamped on both sides of the inner wall of the base 401. The external thread 13 of the screw rod 501 is connected with a nut 503, and the top of the nut 503 is fixed to the bottom of the mounting frame 3. An elastic member 504 is connected to the outer surface of the screw rod 501. The end of the screw rod 501 passes through the base 401 and is fixedly connected with a handle 505. A sliding hole 405 is opened on the base 401, and the bottom of the mounting frame 3 is slidably connected in the sliding hole 405. During the rotation of the screw rod 501, the external nut 503 can drive the mounting frame 3 to slide in the sliding hole 405. The mounting frame 3 is limited by the sliding hole 405, so as to improve the stability of the mounting frame 3 driving the laser head assembly 2 to move. Because the laser head assembly 2 can move on the mounting frame 3, the focus of the light source emitted by the laser head assembly 2 can be adjusted.

[0030] A clamping hole 6 is provided on one side of the mounting frame 3, one end of the laser head assembly 2 is penetrated and installed in the clamping hole 6, grooves 7 are respectively provided on both sides of the inner wall of the mounting frame 3, a locking assembly 8 is installed in the groove 7, clamping grooves 16 are respectively provided on both sides of the laser head assembly 2, the locking assembly 8 is clamped in the clamping groove 16, the locking assembly 8 penetrates the groove 7 and overlaps the back of the mounting frame 3, the locking assembly 8 includes a clamping block 801, the clamping block 801 is clamped in the clamping groove 16 on one side of the laser head assembly 2, the clamping block 801 is slidably connected in the groove 7, and two fixing columns 802 are fixed on the other side of the clamping block 801, the fixing column 802 is outer-mounted with a first spring 803, the first spring 803 is fixed between the inner wall of the groove 7 and the clamping block 801, the clamping block 801 is supported by the elastic force of the first spring 803, so that the fixing column 802 drives the clamping block 801 to clamp into the clamping groove 16 on the side of the laser head assembly 2, so as to facilitate locking of the laser head assembly 2;

[0031] The front and rear sides of the card block 801 are respectively inclined and flat, and the shape of the card block 801 is adapted to the shape of the card slot 16. Two fixing columns 802 pass through the groove 7 and are fixedly connected to the side plate 804. One side of the side plate 804 is fixedly connected to the handle 805. Because the side of the card block 801 close to the laser head assembly 2 is inclined, the card blocks 801 can move away from each other and into the groove 7 after being pressed, thereby preventing the card block 801 from being unable to move and interfering with the installation work of the laser head assembly 2.

[0032] An ejector assembly 9 is installed through one side of the inner wall of the mounting frame 3. The ejector assembly 9 and the end of the laser head assembly 2 penetrate the ejector assembly 9. The ejector assembly 9 includes a top plate 901. One side of the top plate 901 overlaps with the laser head assembly 2, and the four corners of the other side of the top plate 901 are respectively fixedly connected with slide bars 903. The slide bar 903 is T-shaped and slides through one side of the mounting frame 3. A second spring 904 is connected to the outer surface of the slide bar 903. One end of the second spring 904 is fixedly connected to the mounting frame 3. The second spring 904 is fixedly connected to the mounting frame 3. The other end of 04 is fixed outside the slide bar 903, and a through hole 902 is opened in the middle of the top plate 901. The laser head assembly 2 is installed through the through hole 902. The slide bar 903 is driven to move by the pulling force of the second spring 904, so that multiple slide bars 903 can push the laser head assembly 2 through the top plate 901, and then the top plate 901 can pop out the laser head assembly 2, so that the block 801 is misaligned with the card slot 16 in the mounting frame 3, preventing the block 801 from being stuck in the card slot 16 again when the handle 805 is released;

[0033] The portion of the laser head assembly 2 that passes through the card hole 6 is provided with a socket 12, and an anti-dropping assembly 10 is installed in the socket 12. A connecting line 11 is installed at one end of the anti-dropping assembly 10 away from the socket 12. The anti-dropping assembly 10 includes a guide column 101, one end of the guide column 101 is connected to the end of the connecting line 11, and the other end of the guide column 101 is provided with a connecting terminal 104, and the connecting terminal 104 is plugged into the socket 12. The socket 12 is provided with an external thread 13 and is threadedly connected with a threaded sleeve 103. A sealed bearing 102 is installed in the middle of the threaded sleeve 103. Because the threaded sleeve 103 passes through the sealed bearing 102, It is connected to the guide column 101, so that the guide column 101 and the connection terminal 104 will not rotate synchronously during the rotation of the threaded sleeve 103, so that the connection terminal 104 is stuck in the socket 12 without rotating, thereby improving the connection stability between the connection terminal 104 and the socket 12, and the sealing bearing 102 is stuck on the outside of the guide column 101, and a sealing ring 105 is provided in the threaded sleeve 103, one side of the sealing ring 105 is overlapped with the socket 12, and the threaded sleeve 103 can squeeze the socket 12 through the sealing ring 105 when it moves outside the socket 12, thereby improving the sealing connection effect.

[0034] The working principle of the present invention is:

[0035] When adjusting the light source focus of the laser head assembly 2, the fastening bolt 404 on one side of the mounting frame 3 can be loosened during the horizontal adjustment process to disengage the fastening bolt 404 from the slide rail 15 on one side of the laser base 1, so that the mounting frame 3 and the laser head assembly 2 are in a free movable state in the horizontal direction. The mounting frame 3 is pushed to make the slider 402 and the slide seat 403 slide on the slideway 14 and the slide rail 15 respectively. After the adjustment work is completed, the fastening bolt 404 is tightened to make it contact with the slide rail 15, and the mounting frame 3 can be moved. Locking, during the process of adjusting the focus of the light source, the handle 505 can be rotated, so that the handle 505 drives the screw rod 501 to rotate inside the two shaft sleeves 502. During the rotation of the screw rod 501, the nut 503 outside the screw rod 501 can drive the mounting frame 3 to slide in the sliding hole 405, and the mounting frame 3 is limited by the sliding hole 405, so as to improve the stability of the mounting frame 3 driving the laser head assembly 2 to move. Since the laser head assembly 2 can move on the mounting frame 3, the focus of the light source emitted by the laser head assembly 2 can be adjusted;

[0036] When releasing the connection between the connecting wire 11 and the laser head assembly 2, the threaded sleeve 103 is rotated in the opposite direction to rotate on the external thread 13 outside the socket 12, so that the threaded sleeve 103 can be separated from the socket 12, that is, the threaded sleeve 103 drives the guide column 101 away from the socket 12 through the sealing bearing 102, until the connection terminal 104 at the end of the guide column 101 is separated from the socket 12, so that the connecting wire 11 is disconnected from the laser head assembly 2, so as to facilitate the subsequent disassembly and assembly of the laser head assembly 2;

[0037] When removing the laser head assembly 2 from the mounting bracket 3 on the laser base 1, push the two handles 805 at the rear of the mounting bracket 3 so that the two handles 805 respectively drive the two side plates 804 to move away from each other, so that the side plates 804 drive the card block 801 to slide in the groove 7 in the mounting bracket 3 through the fixing column 802, and then the two card blocks 801 are respectively disengaged from the card slot 16 on the side of the laser head assembly 2, thereby releasing the locking state between the laser head assembly 2 and the mounting bracket 3, and then the sliding rod 903 is driven to move by the pulling force of the second spring 904, so that the multiple sliding rods 903 can push the laser head assembly 2 through the top plate 901, and then the top plate 901 can pop out the laser head assembly 2, so that the card block 801 is misaligned with the card slot 16 in the mounting bracket 3, to prevent the card block 801 from being stuck in the card slot 16 again when the handle 805 is released, and then pull the laser head assembly 2 so that its end is disengaged from the card hole 6 and the through hole 902, and the laser head assembly 2 can be removed;

[0038] When installing the laser head assembly 2, the laser head assembly 2 is set up in the mounting frame 3. In the process of pushing the laser head assembly 2, the two clamping blocks 801 can be squeezed. Because the side of the clamping block 801 close to the laser head assembly 2 is inclined, the clamping blocks 801 can move away from each other and move into the groove 7 after being pressed, so as to prevent the clamping block 801 from being unable to move and interfering with the installation work of the laser head assembly 2. Secondly, the end of the laser head assembly 2 passes through the through hole 902 and the clamping hole 6 and squeezes the top plate 901. When the laser head assembly 2 no longer moves, the clamping block 801 is supported by the elastic force of the first spring 803, so that the fixing column 802 drives the clamping block 801 to be clamped into the clamping groove 16 on the side of the laser head assembly 2, so as to achieve the purpose of locking the laser head assembly 2.

[0039] When using the laser head assembly 2, the connection terminal 104 is inserted into the socket 12, and the threaded sleeve 103 is rotated when the threaded sleeve 103 contacts the socket 12, so that the threaded sleeve 103 can be threadedly connected to the outside of the socket 12. Because the threaded sleeve 103 is connected to the guide column 101 through the sealing bearing 102, the guide column 101 and the connection terminal 104 will not rotate synchronously during the rotation of the threaded sleeve 103, so that the connection terminal 104 is stuck in the socket 12 without rotating. At the same time, a sealing ring 105 is installed between the inner wall of the threaded sleeve 103 and the socket 12. When the threaded sleeve 103 moves outside the socket 12, it can squeeze the socket 12 through the sealing ring 105, thereby completing the connection work between the connection terminal 104 and the socket 12.
