[0032] Example 2

[0033] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, the mounting member 201 includes a clamping block 201 a and a moving plate 201 b . The clamping block 201 a is located on the pipe head 102 , and the moving plate 201 b is fixed to one side of the clamping block 201 a .

[0035] When the tube head 102 needs to be clamped, the tube head 102 is first inserted into one side of the clamping block 201a, and then the clamping block 201a is moved to contact the tube head 102, so that the tube head 102 can be clamped, and the movement of the movable plate 201b can drive the clamping block 201a to move.

[0036] Specifically, the mounting member 201 further includes a toothed plate 201c and a first gear 201d. The toothed plate 201c is fixed to the top of the moving plate 201b. The first gear 201d is disposed on one side of the toothed plate 201c. The first gear 201d is meshed with the toothed plate 201c.

[0037] When the movable plate 201b needs to be moved, the rotation of the first gear 201d can drive the tooth plate 201c to move, and at this time, the movement of the tooth plate 201c can drive the movable plate 201b to move.

[0038] Specifically, the driving member 202 includes a connecting disk 202a, which is fixed to one end of the pipe head 102. A sliding groove X is provided on the connecting disk 202a, and the movable plate 201b slides in the sliding groove X.

[0039] The first gear 201d is rotatably connected to the top of the connecting plate 202a via a bearing. The connecting plate 202a is used to support the moving plate 201b and the first gear 201d to prevent the two from deviating.

[0040] Specifically, the driving member 202 also includes a gear sleeve 202b and a second gear 202c. The gear sleeve 202b is sleeved on the outside of the first gear 201d, and the gear sleeve 202b is meshed with the first gear 201d. The second gear 202c is arranged on one side of the gear sleeve 202b, and the second gear 202c is meshed with the gear sleeve 202b.

[0041] The second gear 202c is rotatably connected to the top of the connecting plate 202a via a bearing. The rotation of the second gear 202c can drive the gear sleeve 202b to rotate, and the rotation of the gear sleeve 202b can drive the first gear 201d to rotate.

[0042] Specifically, the driving member 202 further includes a supporting disk 202d, and the supporting disk 202d is sleeved on the outer side of the moving plate 201b, and the supporting disk 202d and the moving plate 201b are movably connected.

[0043] The support plate 202d is provided with a slot, and the tooth sleeve 202b slides in the slot. The support plate 202d can support the tooth sleeve 202b to prevent the tooth sleeve 202b from falling off.

[0044] Specifically, the limiting member 203 includes a ratchet 203a and a pawl 203b. The ratchet 203a is fixed to the top of the second gear 202c, and the pawl 203b is located at one side of the ratchet 203a. The ratchet 203a and the pawl 203b are meshed.

[0045] The ratchet 203a is inserted into the bottom of the support plate 202d, and the ratchet 203a is movably connected to the support plate 202d, and the pawl 203b is rotatably connected to the top of the support plate 202d through a bearing. After the tube head 102 is clamped, in order to prevent the second gear 202c from rotating on its own, the pawl 203b is used to limit the ratchet 203a, thereby preventing the second gear 202c from rotating on its own, so as to limit the second gear 202c. When it is necessary to release the limit on the second gear 202c, the pawl 203b is moved to separate the pawl 203b from the ratchet 203a, and then the ratchet 203a is rotated, thereby releasing the clamping of the tube head 102.

[0046] Example 3

[0047] Reference Figure 1 to Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0048] Specifically, the limiting member 203 further includes a fixing rod 203c and a spring 203d. The fixing rod 203c is fixed to the top of the pawl 203b, and the spring 203d is fixed to the top of the fixing rod 203c.

[0049] There are two fixing rods 203c, and the other one is fixed on the top of the supporting plate 202d. When the pawl 203b moves, it can apply a pulling force to the spring 203d. After the pawl 203b is released, the rebound force of the spring 203d can drive the pawl 203b and the ratchet 203a to re-engage. The fixing rod 203c is used to support the spring 203d to prevent the spring 203d from deflecting.

[0050] Specifically, the limiting member 203 further includes a moving bar 203e and a push rod 203f. The moving bar 203e is fixed to one side of the pawl 203b, and the push rod 203f is fixed to one end of the moving bar 203e.

[0051] When the pawl 203b needs to be moved, the movement of the moving bar 203e can drive the pawl 203b to move, and the setting of the push rod 203f is convenient for the user to move the moving bar 203e.

[0052] Specifically, the limiting member 203 further includes a protective door 203g and a squeezing block 203h. The protective door 203g is hinged to one side of the saliva suction tube 101, and the squeezing block 203h is fixed to one side of the protective door 203g.

[0053] The protective door 203g is surrounded by sealing rings. When the saliva suction tube 101 is placed in the patient's mouth, the protective door 203g can protect the moving bar 203e and the push rod 203f to prevent the patient's saliva from contacting the moving bar 203e and the push rod 203f. The squeezing block 203h is made of rubber material. After the protective door 203g is closed, the inner wall of the saliva suction tube 101 can be squeezed by the squeezing block 203h, so that the protective door 203g is closed more tightly. When the protective door 203g needs to be opened, the protective door 203g can be opened by the user by pushing the protective door 203g forcefully.

[0054] When in use, when the tube head 102 needs to be clamped, the tube head 102 is first inserted into one side of the clamping block 201a, and then the ratchet 203a is rotated. Since the pawl 203b is a one-way limit for the ratchet 203a, the one-way rotation of the ratchet 203a is not affected. The rotation of the ratchet 203a can drive the second gear 202c to rotate, and the rotation of the second gear 202c can drive the gear sleeve 202b to rotate. At this time, the rotation of the gear sleeve 202b can drive the first gear 201d to rotate. The rotation of the first gear 201d can drive the tooth plate 201c to move, the movement of the tooth plate 201c can drive the moving plate 201b to move, and the movement of the moving plate 201b can drive the clamping block 201a to move, and then the clamping block 201a is moved to contact with the tube head 102, so that the tube head 102 can be clamped. At this time, the ratchet 203a can be limited in one direction through the setting of the pawl 203b to prevent the ratchet 203a from reversing and causing the clamping of the tube head 102 to loosen.

[0055] When the tube head 102 needs to be removed, the push rod 203f is pushed, and the push rod 203f moves to drive the moving bar 203e to move. The movement of the moving bar 203e can drive the pawl 203b to move, and the movement of the pawl 203b will drive the fixed rod 203c to move. When the fixed rod 203c moves, a pulling force can be applied to the spring 203d to move the pawl 203b to separate from the ratchet 203a, and then the ratchet 203a is rotated to release the clamping of the tube head 102, so that the tube head 102 can be removed. After the tube head 102 is removed, the push rod 203f is released, and the rebound force of the spring 203d can drive the pawl 203b to re-engage with the ratchet 203a.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
