The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, this utility model is described further, so that clearer, understand this utility model technical thought required for protection.
As shown in Figure 1, 2, for a kind of Mus gag of the present utility model, comprise rack body 10, this rack body 10 comprises the first support 11 and the second support 12 connecting by pivot 31, that is to say, in the perforation that described pivot 31 interts on the first support 11 and the second support 12, so that the first support 11 can rotate with respect to the second support 12 around the axis of pivot 31, thereby rack body 10 is realized, open, close.Between the first support 11 and the second support 12, be also provided with locking mechanism, this locking mechanism comprises by rotating shaft 32 and is articulated in the tooth handle 41 on the first support 11, on this tooth handle 41, along its bearing of trend, is arranged with a plurality of tooth portion; Described locking mechanism also comprises and being arranged on the second support 12 and for the latch fitting 42 with 41 engagements of tooth handle, and the flexible member for driving tooth handle 41 to reset toward the direction of latch fitting 42 is also installed on this rack body 10.
In use, the first support 11 can rotate with respect to the second support 12, to realize the opening and closing of gag.And when gag is opened, by utilizing tooth handle 41 and latch fitting 42 engagements, can make rack body 10 keep opening amplitude, and continue by force retaining opening amplitude without operator, can make opening operation more light, meanwhile, also be convenient to operator and carry out other experimental implementation.
Preferably, latch fitting 42 is ratchet, and by utilizing ratchet to be engaged on the diverse location of tooth handle 41, can make rack body 10 keep the different amplitudes of opening.And by adopting the structure of ratchet, can be convenient to processing and fabricating, can reduce cost of manufacture.
Certainly, described latch fitting 42 is not limited in ratchet, can also be set to other structures, and for example, described latch fitting 42 is for being provided with the profile of tooth portion.By utilizing profile to be engaged on the diverse location of tooth handle 41, can make equally rack body 10 keep the different amplitudes of opening.
Concrete, described flexible member is the torsion spring being sleeved in rotating shaft 32, and a wherein spring arm of this torsion spring is arranged on tooth handle 41, and another spring arm is arranged on the first support 11.And by adopting the design of torsion spring, can make its installation more simple and convenient.
Certainly, described flexible member can also be for being arranged on the spring between the first support 11 and tooth handle 41, or for being connected to the spring leaf between the first support 11 and tooth handle 41.
Preferably, described the first support 11 and the second support 12 all have for being enclosed within collar portion 21, the handle portion 22 on animal teeth; The first support 11, the second support 12 are all usingd pivot 31 and are divided into leading section and rearward end as separation; Described collar portion 21 is positioned on the leading section of the first support 11, the second support 12; Described handle portion 22 is positioned in the rearward end of the first support 11, the second support 12.By the structure of the first support 11 and the second support 12 is rationally set, when opening animal oral cavity, by utilizing collar portion 21 to be enclosed within on the tooth of animal, can make gag be difficult for sliding, so that experimental implementation can be carried out smoothly.
Wherein, the shape of described collar portion 21 can arrange according to the oral cavity structure of animal, so that its suit is more stable, for example, the lateral surface of this collar portion 21 can be made as to inclined plane shape.
Concrete, described tooth handle 41 is articulated in the rearward end of the first support 11, and latch fitting 42 is positioned on the rear end of the second support 12.
Preferably, be also formed with the passage passing for 41 activities of tooth handle on described the second support 12, described latch fitting 42 is positioned at passage.And by passage, can play to the rotation amplitude of tooth handle 41 effect of restriction.Concrete, on described the second support 12, being provided with projection seat 61, described passage is formed in projection seat 61.
In use, operator can be held in the handle portion 22 of the first support 11 and the second support 12, and open rack body 10, then the collar portion 21 of the first support 11 and the second support 12 is enclosed within respectively in the upper lower teeth of animal, after rack body 10 suits put in place, can utilize the mating reaction of tooth handle 41 and latch fitting 42, the first support 11 is locked with respect to the second support 12.And while needing the opening amplitude of adjusting pole body 10, can be along A to pressing tooth handle 41, make tooth handle 41 leave latch fitting 42, just can expand or dwindle the opening amplitude of rack body 10, and after rack body 10 adjustings put in place, unclamp tooth handle 41, now, tooth handle 41 resets and is meshed with latch fitting 42 under the elastic force effect of flexible member, thereby again by rack body 10 lockings.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit with this scope of this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to this utility model scope required for protection.
