With respect to the above-described embodiments, specific implementation processes thereof will be described below by way of example.
In a specific implementation, the sample fixing assembly 110 shown in fig. 2 is adopted for the cylindrical structural feature of the horizontal-spraying lachrymator, so as to form a stable fixing for the horizontal-spraying lachrymator.

The sample fixing and quick-assembling clamp 113 is used for clamping and fixing the tank body of the transverse-spraying lacrimation injector. By way of example, as shown in FIG. 3, the sample securing quick mount 113 in this example is comprised of two semi-circular ring shaped clamp bodies 113a, swing bolts 113b, pins 113c, and wing nuts 113 d.
One end between the two semi-circular clamping bodies 113a is hinged, so that the two semi-circular clamping bodies 113a can rotate relatively; the other end between the two semi-circular ring-shaped clamping bodies 113a is detachably connected through a fastening component formed by matching an articulated bolt 113b, a pin shaft 113c and a butterfly nut 113 d.

In operation, the quick-assembly clamp 113 is opened by only loosening the wing nuts and translating the swing bolts outwards so as to install the transverse-spraying lacrimation injector to be tested.
The present embodiment is directed to the structural features of the safety cover of the horizontal-spraying lachrymator, and the safety cover rotating assembly 120 is formed by the corresponding safety cover sleeve 121 and the first gear 122. The safety cover rotating assembly 120 is controlled by a driving assembly 140 and can rotate relative to the sample fixed quick-assembling chuck 113 under the driving of the driving assembly 140.
The safety cover sleeve 121 adopts an internal tooth sleeve structure and can be integrally sleeved on the safety cover; and the tooth shape of the safety cover sleeve is matched with the tooth shape of the edge of the safety cover of the lacrimation ejector, so that the safety cover can be driven to synchronously rotate along with the lacrimation ejector. Furthermore, in order to ensure that the pressure handle on the horizontal spraying type lachrymatory ejector can pop out when the safety cover rotates to the open state, the corresponding notch is also arranged on the safety cover sleeve 121 corresponding to the notch on the safety cover in the embodiment, so as to accommodate the normal pop-out of the pressure handle on the horizontal spraying type lachrymatory ejector.
The safety cover sleeve 121 thus constructed is disposed on the bottom surface of the top plate 115 with respect to the sample fixed quick mount 113 with the open end facing the sample fixed quick mount 113 and cooperating with the ring 114 to be supported and restrained by the ring 114.
The specific setting position of the safety cover sleeve 121 corresponds to the height of the horizontal-spraying lachrymatory ejector, so that when the horizontal-spraying lachrymatory ejector is vertically fixed in the sample fixing assembly 110 through the sample fixing quick-assembling clamp 113, the safety cover on the horizontal-spraying lachrymatory ejector is just inserted into the safety cover sleeve 121. The safety cover sleeve 121 can drive the safety cover on the horizontal spraying type lacrimation ejector to rotate through rotation, so that opening and closing are realized, and the safety cover sleeve 121 is provided with a notch matched with the safety cover, so that the pressure handle on the horizontal spraying type lacrimation ejector can be normally popped out when the safety cover rotates to an opening state.
Further, the first gear 122 is disposed on the safety cover sleeve 121 to drive the safety cover sleeve 121 to rotate synchronously and drive the pressing handle pushing assembly 130 synchronously, so as to drive the safety cover rotating assembly 120 and the pressing handle pushing assembly 130 synchronously through a driving assembly 140.
The first gear 122 is specifically disposed on the safety cover sleeve 121, and may be determined according to actual requirements. For example, the first gear 122 may be fixedly disposed on the top of the safety cover sleeve 121 by welding.
In order to cooperate with the above-mentioned safety cover rotating assembly 120, the pressing handle pushing assembly 130 in this embodiment is mainly formed by the pin 131, the second gear 132 and the cam 133 cooperating with each other.
The second gear 132 is disposed below the top plate 115 through a pin 131, and is engaged with the first gear 122, so that the pin 131 is driven to rotate synchronously by the first gear 122.
The cam 133 is correspondingly arranged at the lower end of the pin shaft 131 and is correspondingly matched with the safety cover sleeve 121 on the safety cover rotating component 120, the cam 133 can synchronously rotate along with the pin shaft 131, and drives the pressure handle popped up on the transverse-spraying lacrimation ejector to be detected in the rotating process, so that the pressure handle is pressed back into the transverse-spraying lacrimation ejector.
When the safety cover is rotated to be opened, the pressure handle on the horizontal spraying type lacrimation ejector is ejected out of the safety cover, and the safety cover cannot be rotated to be closed; the safety cover can be rotated to close only when the ejection pressing handle is pressed and retracted into the horizontal spraying type lacrimation sprayer.
In the present embodiment, the design of the engagement between the second gear 132 and the first gear 122 is combined with the design of the cam 133, so that the cam 133 can be correspondingly combined with the safety cover sleeve 121 and synchronously rotate to complete the rotary opening and the rotary closing of the safety cover on the horizontal spraying tear-gas sprayer.
Specifically, when the safety cover sleeve 121 drives the safety cover to rotate to an open state, the pressing handle is normally ejected; in the process, the cam 133 rotates synchronously based on synchronous driving of the meshing gears, and the cam 133 does not act on any part at the moment.
When the safety cover sleeve 121 drives the safety cover to rotate and close, the cam 133 synchronously rotates at the initial stage, the cam 133 is in butt fit with the ejected pressing handle in the rotating process, the pressing handle is pushed in at the stroke high point, and the pressing handle is horizontally pushed into the horizontal spraying type lacrimation ejector; after the safety cover sleeve 121 drives the safety cover to continuously rotate (face the closing direction) for a certain angle, the safety cover abuts against a pressing handle pressed into the horizontal spraying type lacrimation ejector by the cam 133; in the process, the safety cover sleeve 121 synchronously drives the cam to rotate continuously, so that the cam is separated from the pressing handle, and the safety cover can rotate to the bottom continuously to realize closing.
The specific configuration of the cam 133 in this example is not limited herein as long as the above-described function can be achieved.
The driving assembly 140 as the power component of the present device is preferably formed by a rotary electromagnet in this example, which is disposed on the top plate 115 corresponding to the safety cover sleeve 121, and drives the safety cover sleeve 121 in the safety cover rotating assembly 120 to rotate the safety cover sleeve 121 and the first gear 122.
The safety cover sleeve 121 needs to rotate back and forth within a certain angle to drive the safety cover inserted therein to rotate back and forth between the open state and the closed state.
For this purpose, the rotary electromagnet in this example is a dc rotary electromagnet, and is configured to rotate by a certain angle when energized and to rotate and reset when de-energized.
Preferably, the rotary electromagnet can be a self-resetting rotary electromagnet, and after power failure, the rotary electromagnet provides necessary restoring force to drive the safety cover and the pressing handle to return to the initial position.
For example, when the dc rotary electromagnet is powered on, the safety cover sleeve 121 is driven to rotate in the opening direction of the safety cover, and the safety cover sleeve 121 can drive the safety cover to rotate to the open state by the rotation angle; when the dc rotary electromagnet is powered off, the dc rotary electromagnet rotates in the opposite direction to reset, and then drives the safety cover sleeve 121 to rotate in the direction facing the closing direction of the safety cover, and the safety cover sleeve 121 can be driven to rotate to the closing state by the rotating angle.

In addition, dry batteries in the battery bin can be used as a power supply, so that the battery bin is safe and reliable, and an external power supply or a connected air source is not needed.
When the direct current rotary electromagnet is in power-off rotation reset, the cam 133 in the pressing handle pushing assembly 130 needs to be synchronously driven to horizontally push the ejected pressing handle into the horizontal spraying type lacrimation ejector, so that the safety cover sleeve 121 can drive the safety cover to normally rotate and close. In this embodiment, it is preferable that the rotation angle of the rotary electromagnet is greater than the opening angle of the safety cover of the lacrimation injector, so that when the rotary electromagnet is turned off and is rotated to a certain angle (the angle value is greater than the opening angle of the safety cover of the lacrimation injector), the cam 133 is driven by the rotary electromagnet to abut and cooperate with the ejected pressing handle (as above), and pushes the pressing handle at a stroke high point to horizontally push the pressing handle into the horizontal spraying type lacrimation injector, and then the safety cover of the lacrimation injector is driven by the safety cover sleeve to continue to rotate and cover the pressing handle.
In the above-described solution using a dc rotary electromagnet as the driving component 140, the control component 150 in this example is preferably configured by a corresponding counting controller. The counting controller is arranged on the top plate 115, is connected with the direct current rotary electromagnet in a control mode, and is configured to control the power-on and power-off states of the direct current rotary electromagnet; the counting controller counts the number of times that the dc rotary electromagnet performs one power-on and power-off operation, thereby serving as the number of times that the safety cover is checked.
And a corresponding display is also arranged on the counting controller according to the requirement, and the specific counting times can be displayed.
Finally, the cover 160 in this example is preferably a clear plexiglass plate to make the device integral cover, which has no bottom and no top surfaces. The cover 160 with the structure is covered between the top plate 115 and the bottom plate 111 on the sample fixing component 110, so that the sample fixing component 110, the safety cover rotating component 120 and the pressing handle pushing component 130 are arranged in the cover, the running state of the device and the test times can be conveniently observed, the closed state of the test device can be ensured, and the injury to testers under the condition of lacrimator spraying is avoided; in addition, during the testing process, the testing personnel can adjust the driving component 140 and the control component 150 which are positioned outside the housing 160 at any time, so as to ensure the safe and reliable operation.

At this time, in the initial stage of the directional rotation, the protrusion of the cam 133 horizontally pushes back the pressing handle sprung up on the lateral-spraying tear sprayer; after that, the safety cover sleeve 121 drives the lachrymatory ejector safety cover to continue rotating to a certain angle, the cam 133 synchronously continues rotating, the upper protrusion of the cam is separated from the pressure handle of the horizontal lachrymatory ejector, and then the lachrymatory ejector safety cover can continue rotating to the bottom (the specific process is as above, and is not described herein).
Finally, the controller counts the number of times the rotary electromagnet 13 completes one power-on and power-off operation, displays the count, and automatically terminates the test after 100 times of display.
